My Razor has been fine. i’ve had it since April (it was free). Never had a problem with it not working. The battery lasts days on end if I am somewhere with strong constant reception. if I am somewhere with a weak signal it only lasts about 12-16hours.
I’ve been happy with it though.
Edit- then again I am not a phone nerd. The previous phone I had was an LG flip phone that didn’t even have an outside screen, or ANY features. It was a phone, and that was it.
