Basically, you can't write anything with this keyboard unless you don't mind typing one character per second. It's really almost impossible to type faster.

I gave it two stars because I didn't really buy it to write long texts or code with this little thing. I bought it to show my friends that I have a flexible keyboard, or maybe as a small gift for a friend. From this perspective, it works, meaning it actually wraps around itself and all the keys actually work on all the devices I tried (a Mac Mini, a Dell laptop with Ubuntu, and an Android phone). It's just very difficult to write more than 4 or 5 characters in a row.
