Last year I bought the KDLINKS 700; a very nice product but with some limitation and poor documentation.
They went back to the drawing board and released a highly improved version pretty much corrects most of the limitations and provides a better, clear and faster user interface.

The new box design permits the easy installation of SATA disk (up to 3 TB with this software version) that can be used to store movies, pictures and music. A USB 3.0 MALE connector; when plugged to a computer or laptop it becomes an external storage so it is fast and easy to move files to and from the device.

As in the previous version, KDLINKS 720 still keeps two USB ports for reading and writing from external devices. You can play anything including BD folders with excellent quality, or just copy, move or manage folders and files.

WI-FI is faster than previous version; you can play DVDs or ripped movies from a remote server; but speed is not enought to play BD folder. You can use the RJ45 connector to plug to the network.

As in previous version; the unit worked fine with every ripped format I tested (MKV, AVI, MP4, DIVX, VOB and a few others) with excellent quality (sometimes you can't tell the difference from the master). It was also capable of playing a PAL DVD on an NTSC TV.

The only unresolved issue are BD menu; but let's hope it will improve with a new software review. A capture application for recording will also be a welcome addition.

In brief; a highly recommended and useful product if you like to keep your movie collection handy and with perfect quality.

UPDATE: Sept 2017

Apparently I was a bit too hasty in posting my original review for the KDLINKS HD720. I believe a product should last longer than the overall very minimal use that this player received. It still has that “new” product
smell and the protective plastic is still adhered to the top. In all honesty, although I have owned this player for 2 years, the player itself maybe has had 36 hours total playtime. I was overly anxious to review a media player that could read from an HFS+ HDD, as I have yet to find another company that makes one.

After having this player in storage for 4 months, I connected it to my TV with a friend over. They were tired of hearing me brag about what a great player it was. Immediately after turning it on, the HD720 player display went to ‘NUPGRADE’ and locked up the screen on the TV. So I secured power and tried again, ‘NUPGRADE’ again. Needless to say, my friend was not impressed. I explained it was probably just a firmware issue or required a hard reset. I wasn’t overly concerned, as the player performed well the last time I had used it. I emailed the distributor NBOX the following day expecting a quick fix, and this was their response:

“The issue is due to the damaged circuit board, no easy to way to fix it. It can still work as USB 3.0 high speed HDD docking station if you connect it to PC. 

Do you want to upgrade this model to A400 4K model? I can give you a big trade in credit for this not working unit even you bought it over 2 years ago. We can do 80% credit for you towards the new device A400.”

I went to Amazon and clicked on all the one star product reviews concerning the HD720 player and found this NUPGRADE issue repeated over and over. I can only assume that most purchasers like myself were at first thrilled with the player and gave it great reviews but most fail to update their product review to reflect what a major disappointment the KDLINKS HD720 turned out to be.

The HD720 was stored for future use in the original packing material it came in. As I mentioned previously, the player was rarely used. The problem is I purchased the A400 earlier this year because I was impressed with their original product, and I’m sure that the cheap electronics that KDLINKS used in the HD720 were used in the A400 as well. It’s only a matter of time before that player decides to stop working. I intend to update my original review of the A400 as a cautionary tale to others to reflect this. Besides, unlike the HD720, the A400 is strictly Android based and can only read from an NTFS or FAT formatted HDD, which could pose a problem if you are a Mac user.

We all have electronic computers and players with “circuit boards” that take a beating day after day and still continue to function with no difficulty, but the HD720 media player received no hard use whatsoever, in fact, it was handled with the utmost care. I have subscriptions to NETFLIX, HULU, HBO, AMAZON PRIME, so I used this player mostly to organize my music, photos, and some obscure video files I throw in.

As far as other media players that can read from an HFS+ HDD, I cannot recommend any at this time. Personally, I have not been able to find one listed on Amazon. It hearkens back to a day when it was impossible for a Mac user to find common software available only to Windows users. If anyone can recommend a reputable media player that can read from HFS+ to me then please let me know. For Mac users there is a way around this, albeit kind’ve frustrating, what I can suggest is backing up your media files and then reformatting an external drive to NTFS. Then transferring the files from the HFS drive to the NTFS drive. This of course would require either a Windows emulator on your Mac, or purchasing an inexpensive PC laptop with a software program that can read both drives. Overall, very frustrating, but with some research, it is possible. Amazon has many media players listed that can read from an NTFS HDD. Another option is to format a drive to FAT32 or exFAT which both Macs and PC’s can read, but with a few caveats. One being file size constraints with the FAT32 (single files can’t be larger than 4GB), and exFAT being too slow.

I would be hesitant to purchase another KDLINKS media player considering the experience I have had with this one.

KDLINKS and their distributor NBOX are fully aware of the HD720 ’NUPGRADE’ issue and should either fix the problem or stop selling a defective product to trusting consumers.

Thank you.

No media player is going to get 5 stars. They all have their advantages and quirks, and this one is no different. It makes the 4th player I have tried, all from Amazon, because of their great satisfaction policy. The previous unit was a WD Live TV player, earlier version, that lasted less than 3 years and had to be repaired under warranty, and still did not have sound on streaming programs.

The KDLinks HD 720 Full HD 1080 has some great features and could be made better with a few changes. I will get the CONS out of the way first to diffuse marketing hype and then the PROS that make this player the best choice yet, and have recommended.

CONS:
1) Panel controls are without any contrasting color for the recessed graphics or letters, they are near impossible to read without direct light on them.
2) All the hype about the USB 3 connection is useless. After about 2 dozen attempts to connect to speed up the downloads (by transferring to my laptop and then to HDD - laptop has a USB 3 port, it only came up in OTG mode three times and only connected in File Explorer twice for accessibility to internal HDD. You cannot have ANYTHING connected except the USB cable, just like the picture shows. However, the first attempt with my older laptop, with USB 2 ports, did show all three drives. So, the claim that you have to throw all the old USB 2 cables away is misleading. The USB 3 "B" connector is different but as it is very iffy on connectivity it would have been better to make the 2 USB 2 ports into USB 3 ports and forget this useless feature. A WD 4 TB USB 3 My Book here on Amazon is a better value and more practical than this "feature."
3) The two USB ports are only USB 2 and show there datedness when USB drives are connected. (Slower access than previous USB 3 equipped media players.
4) For claimed gigabit connectivity, downloads are painfully slow for full HD (1980X1080) at about 5 - 6 MB/S. This compares to the expired WD Live TV that would at least transfer at 10 MB/S. (Note: I do have a gigabit computer Ethernet card and a gigabit NETGEAR Network switch.) I eventually transferred to a media server that solved the upload issue, now transferring at 60-65 MB/S and need to select which drive to access.
5) Cannot access drives when unit is turned off. Some media players, such as WD Live TV and others, have active Ethernet connectivity when unit is not in use and can be used as network storage.
6) Speaking of turning the unit off, if you do not have your TV on and the HDMI input selected for the unit, it will not turn off UNLESS you are at the HOME screen. (Showing HOME on unit display.)
7) Not really a CON but this unit, as well as others I have tried, can also be easily confused by doing too much too soon. Heed the warning that it is like a computer booting up. It must recognize all drives, Ethernet and Wireless Plug-in before use. All the icons in lower right of screen, as messages in upper left screen, must show before use. Otherwise it will freeze and you may have to do a power reset (unplug power cord from rear, wait about 30 - 60 seconds, and plug in again). I had a HDD and two USB 3 HDDs and it had to see the Each USB HDD (same message for twice), HDD, and initialize Wireless Plug-in (even though I am wired Ethernet), before continuing.
8) Closed Caption controls are dependent on your converter settings. Some ISO image files that were converted a few years ago work and some do not. On the ones that work, one cannot cursor over to font and background controls to adjust for the movie.
9) It does not have Amazon Prime Streaming available as a built in feature or an available plug-in.
10) It would be a nice feature to enable a clock display when not in use.

PROS:
1) First, it plays all the formats that I have put on it from converted DVDs and recorded broadcasts (iso, vob, ts, mp4, mpg). Some broadcasts have 1980x720 at 59 fps in .mpg format. It was easy to set up and did not have to use the panel controls for a black screen.
2) Remote is easy to use and would be nice if colored buttons for file functions were labeled (especially Green as it is not pure enough on screen).
3) Video is GREAT! The same files that looked good on the expired WD Live TV were MUCH CLEARER and better quality on this media player. Upscaling the standard DVD to full 1980X1080 is even better and looks like theater quality. Have seen Blu-Ray and cannot see difference except more royalties for SONY.
4) This unit can take a 6TB HDD. I tried a WD Green and Blue series, both 6 TB and formatted NTFS, and worked fine. Drives install easily in holder and slide in and out with finger grips.
5) USB HDD worked fine also. I had two WD My Book 3 TB drives. Oddly, they show up first for logical drives in Media Player file system and on network File Explorer. Such as: USB 1 is C: drive, USB 2 is D: drive and internal HDD is E: drive. This 12 TB of storage.
6) A USB Hub was used and there was no difference in performance. As the ports are USB 2 grade, there was no performance difference between using a USB 2 and USB 3 Hub.
7) Unit will respond to a wireless keyboard. It does take you to the normal entry screen for the remote, but can be faster in searches (files and web, user names and password entries.
8) Browser is better than many with ease of use and actually being able to look things up. However, It is not powerful enough to run Amazon Prime streaming.
9) Weather add-on is great.
10) DLNA compatible and hooked up to older Cirago NUS2000 and newer Qnap TS-431 file servers without problem. Both units purchased on Amazon.
11) Shortcuts feature allows less keying to reach desired location on network. Drawback is only root directories can have shortcuts. Maybe can be modified in some other screen.
12) Optical output works great into stereo input.
13) Unit responds to security feature from file server on who has access with user name and password for directories and folders. In otherwords, you will see many folders but only have access to those that are authorized by user name and password.
14) File transfer feature works well for attached USB and internal drive. Very fast. However, does not like to transfer ISO files and failed each time.
15) Great poster art feature. Tried and looks great but too time consuming for the many titles accumulated and not practical for me for TV series.
16) Probably one of the better values on Amazon or anywhere else.
17) Great customers service. I will call him "Mr. E" and say he was very prompt, within a couple of days, to respond to my queries. He expressed the many virtues of the codecs that play the variety of formats. There was commentary on adaptability of why USB 2 were not USB 3, which I do not accept and is probably working within the accepted guidelines of his employer. He was very polite, thorough, and have no issues in the manner his responses were conveyed.
18) Music plays fine from local or remote network storage.
19) The unit came well packaged to prevent damage. All USB cable, HDMI cable and power adaptor came in a separate box and was well placed on outside of shock-proof internal packaging.
20) Instructions were easy to follow but disappointed that online version was not more detailed with extra information. It is the same as the included booklet.
21) Media Player name can be changed to find it easier on File Explorer Network.
22) Streams movies and files to other computers.

I do not have "3D" so cannot comment on this feature. However, based on what I see so far, I would venture to say it will be good also.

I would recommend this player.
