First day we got this it, we charged it and wasn't working, but after reading the other reviews, it was the tiny tape on the battery which caused the issue. Once removed it worked. But on 3rd attempt to use it, it was fully charged but always turned it self off. Even when we plugged it into the mains and turned it off we simply couldn't get it to give out a constant signal and allow devices to connect to it. Too late to return this unfortunately.
