So, I ordered this keypad about 3 weeks ago and it arrived 1 week ago. I had enough time to play with it as I received it during the holidays, and I had to say, I'm really impressed by this keypad. First off, let me address the unanswered question asked by me in this forum. Yes, the keys can be set using the software to light up individually when pressed, you also have some other led settings you can tamper with. The rgb lighting is really fancy, for me at least, as I don't own and have never owned any other products with rgb lighting except this.
The build quality overall is really good. The keypad feels really solid as the top panel is made out of metal. ( correct me if I'm wrong ) The keypad do slip around a lot due to the smooth plastic bottom surface, and I really recommend using the included sticky tape to stick it in place.
All the different Cherry MX switches are a nice addition. I've messed and played with all of them and I've gotta say the browns are my favourite with blue being a close second. Antecer even included a little box to store all of the switches neatly.
There's also an included USB cable so you don't have to buy extra cables to use it.
One little thing though is that the 3 metal buttons are really hard to press, they require a lot of force to press and I'm honestly not a fan of it.
All in all, I highly recommend this keypad over the others, even the official ones, though the buttons on the official ones are way nicer. But the official ones are way more expensive and doesn't come with as many accessories as this.
