>>5796160Yes, I just rely on muscle memory and lay my hands on it and type on it like a regular keyboard without looking. It's not difficult. Takes maybe a day or two to get used to layout. It also comes with a set of black and white stickers you can place on the key caps, but I didn't do it because I don't need it. I did rearrange the key caps to make the different groupings of keys more noticeable.
You can also buy new key cap colors online from aliexpress, kbdfans, or some other mechanical keyboard enthusiast website, but only if you know how mechanical keyboard key cap profiles work since key caps come in different shapes. It looks like the default key cap for all Koolertron keys is OEM R2 if R1 starts from the top, or R3 if R1 starts from he bottom. In the picture, R1 starts from the top row, so it will be OEM R2 in the picture. That being said, you can still use any other key cap shape if you want to make the key pad more ergonomic.
>>5796321Yea, it's expensive since that's the only keyboard of it's kind on Amazon. It probably includes import shipping since most of keyboards of similar type are on Aliexpress.
