RE: A Minimalist Portable 5$ Keyboard, Is It Reliable?

This is one of the cheapest devices I've ever seen. You shouldn't expect too much from something at this price. But I think this product is beyond its price. Usually using the keyboard for a long time causes wrist pain, and from what you said, you didn't experience that. I've never used a mini keyboard before because I mostly play games and code, and I don't have small fingers. But at this price I'll buy any keyboard because I want to have it on hand in case my keyboard breaks.
