Works good, with minor annoyances

Reviewed in the United States 🇺🇸 on March 29, 2012

Style: 4 Port Audio w/ CablesVerified Purchase

Purchased this switch to replace an old Belkin PS/2 unit. I was not sure about this switch when ordering, as many other reviewers have reported serious problems getting it to work. But, this unit has one of the best ratings I found and I took a chance.

I did have some issues getting it to work, but relatively minor ones. Of the three machines (2 Win XP, 1 Win 2003 server) I've attached to it so far they have all worked. The 2003 Server machine loaded a couple of drivers upon logging in, but worked fine. One of the XP machines worked perfectly (didn't even have to load any drivers). The other XP box didn't work at all initially (no keyboard, no mouse). I plugged in an old PS/2 keyboard (also leaving the USB plugged in through the switch). I was able to use the PS/2 keyboard to log in once the login screen came up. Windows then proceeded to load about 20 drivers and then both keyboards were working. I then unplugged the PS/2 keyboard and the USB works fine.

Once I got past that, the switch has worked very well. Just a couple of minor annoyances. I'll just list out the pros and cons:

Pros:
-----
* No transformer to plug in. The unit is powered via the USB port, and this means there is one less boxy transformer to find a space for. Haven't had any problems with this.

* The included cables are nice. The keyboard/mouse both go through a single USB port on the computer, and there is just a single plug at the switch end.

* The keyboard switching works great (ScrLk, ScrLk) and switches only between active ports (ie if the computer on port 3 is not on, it will not stop at that port when switching). On my Belkin switch the key sequence was much more complicated (Ctrl-Shift-Alt, Port#, <enter>).

* No drivers required. They do include a CD that has a program you can optionally install. This allows the use of alternate key sequences to switch ports and also allows you lock the audio to a specified port.

* Four separate buttons on top of the unit to switch immediately to any port. My Belkin unit had a single button, and if you wanted to go from port 1 to 4 you had to skip over 2 and 3 (or use the keyboard shortcut). I like the four separate buttons a little better, but it is harder to locate the button you want without looking directly at it (I have it on a shelf under the desk and seeing the buttons isn't easy) or feeling for it.

Cons:
-----
* The biggest thing I don't like about this switch is its physical layout. Who thought it was a good idea to have cables sticking out of four sides of it? They certainly didn't do it to save space. My old Belkin switch had all the cable connections in the back of the unit and a single button on the front (a much sleeker setup). The switch itself is a little bigger than this unit, but actually uses less space due to the cable configuration on this one. The one possible upside to this setup is that the console cables (the cables from the keyboard, mouse and monitor) are located on the front of the switch. Since USB keyboard/mouse are hot swappable (don't try that with PS/2), I suppose you can more easily change your keyboard/mouse. Even given that, it still would have been better to put all four computer cables on the back of the unit.

* This is a very minor thing, but occasionally when switching between ports (or at Windows startup) the keyboard/mouse will take several seconds to start working.

* Another minor thing: The audio cables are separate from the KVM cable, and I would have liked it better if they had been molded all into the same cable. I suppose this way is more flexible if you're not using the audio feature of switch, and a few zip ties work to accomplish almost the same result.

Set up is Easy / Reliability, Not So Much

Reviewed in the United States 🇺🇸 on June 9, 2021

Style: 2 Port USB Audio w/ CablesVerified Purchase

Over the past several years, I have purchased three TRENDnet TK-209K KVM switches. I love the convenience of using one monitor, keyboard and mouse to control my two laptops. I have one laptop for work and one laptop for personal use. Switching between the two is a breeze by either using the push buttons located on top of the switch or via the hot key (Fn + Pause/Break).

For less than $25, it's a great deal. The set up is straight-forward. Connect the cables to your computers and plug it in. I use a Logitech wireless mouse (M510) and Logitech wireless keyboard (K35). I just plug the USB unifying receiver dongle into the KVM switch and away we go. The cables are configured for VGA, so you will need to purchase a VGA to HDMI adapter if your computers use HDMI for the output to monitor display.

As I mentioned earlier, I have purchased three of these TK-209K switches over the years. Unfortunately, they are not built for longevity. I find they last about two years max before they give up the ghost. But for $25, it's not a big deal. I'm sure there are more reliable KVM switches available, but I really like the hot key swapping between computers. When it works, it works well. When it breaks, I just buy another one. When the new one arrives (next day shipping on Amazon Prime), I don't even bother with installing the new cables. I just unplug the cables from the broken unit and plug them into the new unit. I'm back up and running within minutes.

Overall functionality is good. Overall durability is lacking, but what do you want for $25?

UPDATE: July 6, 2021 - 33 days later the new unit failed with the same problem: "USB device not recognized". Unfortunately, the return window expired three days ago. Time to invest in a different KVM switch.

UPDATE: July 7, 2021 - I decided to call Trendnet's tech support line to see if they could help in fixing the USB device error I encountered yesterday. To make a long story short, we were able to resolve the issue by unplugging all the cables that connect to the Trendnet device. After plugging them back in, the device is working once again.

Good for simple usage, poor for advanced settings

Reviewed in the United Kingdom 🇬🇧 on December 16, 2014

Style: 2 Port USB Audio w/ CablesVerified Purchase

Well I have to say that I'm highly disappointed with this one...
The idea was great, and I was hoping to switch my screen, mouse and keyboard from my professional laptop to my personal desktop. On the principle, it works, you will be able to share your screen and peripherals between 2 computers. It's probably not the best KVM Switch I've ever seen, but for this money it looks fair.

However I felt like there were too many negative points to keep it:
- Some other reviews mentioned it: it doesn't remember the monitor aspect ratios. It is just unbelievable to change the ratio of the display every time you reboot your computer (once a day if you turn it off as I do).
- Every time you switch (through the manual button or the hot key) an army of "dong" is heard for all the peripherals getting reconnected (wait I thought they were already connected?)...
- As I have an usb on my keyboard, I have tried putting in my mouse, and using the spare usb for a Logitech Webcam that could be shared. It basically crashed most of my softwares using the webcam, and could never work... A bit sad it would not work!
- Cable management: the KVM Switch is not particularly handy for that as you've got robust cables going from the front, behind and sides... You need quite an important space for it, while I was hoping it would save me some space.
- I was always getting the message that the USB could be faster (they were plugged-in through the correct USB...) so I don't know if those USB are good (are these really 2.0?).
- My main screen was starting to make a strange noise when connected through the KVM. Never had this before.

Finally requested a refund after 2 days using it... I'll probably find another way to share my peripherals. If you're a basic user looking for a simple solution (with same ratios between computers/screens?), it might suit you. If you're more demanding, then don't take it.

Trendnet switch kit - brilliant!

Reviewed in the United Kingdom 🇬🇧 on August 2, 2014

Style: 2 Port USB Audio w/ CablesVerified Purchase

This is a marvelous device that I had never heard about till I came across it in a magazine recommendation. Looking on Amazon there were cheaper units that had mixed reviews, but this one at twice the price (£20) had nothing but five star ratings, and this is the one I went for. It arrived within 3 days, and despite there being no real installation instructions - only a printed diagram showing which of the supplied cables goes where, I had it up and running in 10 minutes. I now have both my XP and Win7 towers running through the same 24" screen, wireless mouse and keyboard, and speakers. I have both towers running simultaneously, and little switches on the top of the unit marked 1 and 2 allows me to switch between computers with ease. As far as I can see there is no downside to this device, I can work on one computer doing one task whilst the other is burning a disc or similar, switching back and forth between the 2 computers at will. I have no hesitation in recommending this unit to someone who wants to 2 towers together.

Nice piece of kit

Reviewed in the United Kingdom 🇬🇧 on September 27, 2014

Style: 2 Port USB Audio w/ CablesVerified Purchase

Nice piece of kit, and works after a fashion. I've An Asus laptop running at a std res which recognises my 24" dell monitor perfectly (when it's plugged in directly). however, the dell needs to be shared with my desktop too and hence why I bought this item.

So does it work? yes.... connect everything up, but when the laptop is selected the first time, it defaults to low res. Unplug the connection, wait for the laptop to "refresh" and then reconnect. the monitor then switches to hi-res. hurrah.

HOWEVER, with the dell connected to the laptop via this kit, you can visible see the dell refreshing... it's a line running left to right/right to left moving up the screen from bottom to top - which isn't present when it's connected directly to the laptop. and yes, after a while, you get used to it, and do not notice the refresh line (as I call it).

Yes, it DOES work!

Reviewed in the United Kingdom 🇬🇧 on March 18, 2015

Style: 2 Port USB Audio w/ CablesVerified Purchase

After trying out another brand of KVM switch, purchased twice (2nd one was a replacement) from another shop, neither one of which worked, I began to think KVM switches probably just didn't work. However, this one proved me wrong.. Delivery and packaging was fine. Set-up was straightforward and it all works really well. Occasionally I have to press the port-switch rather than just use the Ctrl+No. There is then a short wait while it switches to my second computer. The wait, however, may have seemed longer due to my bad experience with the previous non-working KVM models. Apart from being neat and the cables sufficient, this model has shown itself to be absolutely ‘just the job’.

Excellent Product

Reviewed in the United Kingdom 🇬🇧 on June 25, 2012

Style: 4 Port Audio w/ CablesVerified Purchase

This is an excellent product that does what it is supposed to do, and some more.
I have it controlling computers running AppleOS, Windows 8, windowsXP and Windows 7.
I attached a Belkin 7 port usb hub to the usb unput and connected an external cd drive, keyboard, mouse, external speaker and a 32GB flash drive. When I switch between systems all devices are available as though they were connected directly-I have not tested the Mac yet but have no doubt it will work. And all at a reasonable price.
Well Done Trend.

Addendum
I have this produce since 2012. It is now June 2013 and I have had no issues with this product. I have moved it around from room to room. It allows me to control several computers from a distance using usb extenders. Buy One!
