Since I haven't been able to confirm its operation, I'm selling it as junk. I bought it intending to use it back then, but I got bored within a week, so I didn't use it much. The battery will be removed before shipping, so you'll need one CR2032 battery if you want to use it. I haven't checked if it works. I cannot accept returns if it doesn't function. Please consider this only if you understand and accept these conditions.
