I want to preface by saying Ajazz provides some of the best keyboards for those new to the custom keyboard game. I purchased the AK820, in the white color with the white switches. My first ever mechanical keyboard and it is absolutely amazing. It makes typing very enjoyable. I also loved messing around with the different functions of the back light display. I will admit though, that I was tricked into buying this keyboard. I thought that for $35.99 USD, I would be getting the Bluetooth keyboard with the different connectivity modes, but you will not get that with this model. This model is wired, as there is no Bluetooth dongle or any button, keyboard button to press to connect wirelessly. Nothing in the manual mentioned Bluetooth connectivity, and I was slightly disappointed. But besides that, this is a great keyboard and in my opinion, is better than an official gaming mechanical keyboard that my brother got with his prebuilt bc bundle. That keyboard doesn’t compare to this one, this one is much smoother and more enjoyable to use than that one. GREAT buy for the money, but note that this isn’t the Bluetooth model, only the wired one.
