    1.0 out of 5 stars 2 bad eggs in a row - don't waste your money on this trash
    By N. A Smith on August 10, 2021
    When I first got this, I was thinking it was going to speed up my productivity a fair bit, especially with all the copy paste and use of special characters like ÷ or ≈ that I have. Getting the key mapping and macros set up for these was easy enough to do. After a few hours, I wanted to make an adjustment to replace something I didn't like (on my end, such as replacing control+Y with control+S instead). No problems there. I like the brightness of the LEDs and the rich color quality that they have. When set up, it's easy to use.

    After 2 days, however, it went haywire. I press the button associated with control+K to clear my selection in my image editing program and, strangely, it's only as if I pressed shift+S instead, for sheer mode, and the image also moved to the right by one, as from pressing the right arrow key. Somehow, the firmware got changed. Disconnecting, waiting a few seconds, then reconnecting it fixed it, oddly.

    About 2 more days later, I wanted to make another adjustment. Communication error. I tried several times. Communication error. I disconnected the USB cable, waited a few seconds, reconnected it, then tried again. Communication error. I tried another disconnect and reconnect, doing both ends this time. Communication error. I tried using device manager to update the driver. No update available and it's coming from Microsoft as there is no driver download from the manufacturer. So, thinking the driver may have been corrupt, I uninstalled all 3 keyboard instances that show up (even though I only have 2 keyboards, disconnected both keyboards, restarted my computer, reconnected the keyboards, my main one first. I see one keyboard showing up. Connect this macro keyboard and I now see 3 keyboards showing up. 3? There's only supposed to be 2! So, I tried making that change again. It worked this time and I was able to do it. Then, about 2 more days later, it wouldn't do anything, at all. Press the button I have assigned to the ÷ symbol (hold alt and, on the numpad only, type 0, 2, 4, then 7 in that order, then release alt (the number is after the ASCII position); the numbers above the letters cannot be used) and nothing happened. Repeat on my normal keyboard doing the holding alt method and it works just fine. It's not a program limitation, it's this macro keyboard. After another system restart, I was able to get it to communicate again so I can make the adjustment.

    2 days later, it stopped responding again where pressing the buttons didn't work, doing absolutely nothing. 3 strikes, I got with Amazon to return it and got a replacement. Amazon did very well with that. I got the replacement, got the key mapping redone, and better than I had before, and everything was fine. I go to bed, turning off my computer as usual, then I wake up... to find that the keyboard's colors are not set right. I originally had it on rainbow, option 2, but it somehow got changed to option 3 from simply turning my computer off then back on again. I got that fixed, but the replacement was behaving weird. I would randomly see it doing what it does when you disconnect then reconnect the device, with the white light flashing where the third from the left key at the top row is, then going into the color pattern cycle as it's supposed to do. After about 4 hours of normal use, I saw that the color pattern somehow changed. Green and magenta got added in when I never set those colors. I went into the AMAG program to try to correct this. Communication error! I tried the usual disconnect/reconnect and that, by itself, fixed the colors where it was behaving like I expected. But, just trying to do a connect to it to see if it's even working right, surprise! Communication error! It would absolutely not communicate with the software whatsoever. I tried disconnecting it then try connecting, but I get a different error stating that the device is not found, of which I'd expect. I reconnect the USB and try to connect with the software. Communication error! I tried switching to a different USB port, a direct connection on the motherboard. Communication error! I've run out of ideas on what I can do on my end to fix this. I tried clicking "update" and the program would just go into an infinite loop (100% CPU usage on one core) and stop responding, but only when I'm on the "custom macro" tab. Even a half hour later, it's still stuck on that. The other tabs just show an error.

    Normally, a bad egg is about a 1 in 300 chance, but 2 bad eggs in a row is a 4 sigma anomaly, a massive statistical outlier. The quality control at the factory seems to be poor to nonexistent for this product. This product is a waste of resources. This is under Windows 10 Pro with 192 GB of RAM, a 32-core processor, a GeForce 2080 Ti... it's definitely not my computer, it's this piece of trash keyboard with defective firmware that's at fault. Do not buy. There are better options out there and I'm starting to look into them instead.

    The 2 screenshots are of the communication error I keep getting when I click on "connect" in AMAG, and also device manager for the driver tab. There are no updated drivers, even though it's 15 years old.

    4.0 out of 5 stars Perfect little keypad!
    Reviewed in Canada on March 29, 2019
    I was very interested in getting an ortholinear keyboard, but didn't want to jump in without trying it out first. Couldn't find anyone local with a grid-like keyboard so I went looking for a flat numerical keypad that I could turn on its side. I eventually found this. Couldn't find much information online about it, but figured it was worth a shot. It definitely was.

    I currently use it for gaming, but will be setting it up as a macropad for programs for work as well. It has also inspired me to build my own keyboard (which I am currently in the process of figuring out what to get).

    The software for it was a little hard to hunt down, but there's a link to it on a YouTube video Koolertron has posted about this keypad. The program file is AMAG.exe and is called AMAKeyboardClient. It works great, though just now I seem to be unable to connect to the keypad through it. I'll edit this review in the future if this becomes a persistent issue. I'm sure if you're already into keyboards there's some other program that would work just as well, but I'm quite new to this and didn't want to risk it!

    It claims the 65 keycaps included are top-printed, but they are double shot, and of pretty decent quality. They're on par with the Corsair K70 keys I would say. The blank keys however, are horrible. I won't be using them on anything. They feel gross to touch. Also I was missing one 1u sized key, and one 1u key was significantly discolored. Overall not a huge deal, but I would have preferred to use the blank 2u key as my spacebar instead of the "0 INS" key. The blank keys feel like trying to assemble a LEGO kit with dollar store bricks.

    I've used a Razer keypad in the past, but got rid of it after only a week or so of using it. It was far too uncomfortable, and the lighting was greatly disappointing. The lighting on this is BRIGHT (and adjustable!). I use my wallet as a wrist-rest while using it right now as it can get a little uncomfortable after using it for a bit. I'll be getting a proper rest as well.

    Very happy with this keypad overall, I'd definitely recommend it for gaming or work. Would be a great stream deck as well.

    3.0 out of 5 stars Flawed but I like it
    Reviewed in Canada on August 27, 2019
    I like this keyboard a lot, its fun to use and has a very satisfying sound and crunch. The programmable keys are great for working at my job. I can easily have all my animation shortcuts available and never need to use my main keyboard. I only have a few problems with it.
    1- It's doesn't sit flat. IT wobbles on any flat surface a lot which can be very annoying.
    2- It is a bit sore for the wrists because its so high up which can be annoying if your working long periods of time.
    3-Actually programming the keys can be a bit difficult to figure out for the first time. The software is not really user friendly, and if you never dealt with macros before that can be very confusing.

    I fixed the first two issues with a spongy mouse pad with a wrist pad, although i still get a bit of pain in my wrist. The 3rd issue just takes some time and googling.

    I do really like the keyboard overall.
