This thing is a horrendous piece of shit. Aside from all the issues with FM reception, no battery warning, Bluetooth randomly dropping, suddenly it's started asking me for a PIN for Bluetooth. There's no way to find a PIN or enter a PIN, so that's $110 speaker completely bricked.
Avoid this speaker, quality and reliability are non existent, I have had 3 and they all have issues rendering them unusable. The charging board overheats and the speakers shuts down, there is connectivity problems and a lot of radio interference cutting out the signal, one of the speakers does't even charge while in use, and another sometimes does't even turn off, until runs out of battery! The rechargeable battery is non replaceable making this product disposable. Like with many online Chinese products out there from unknown companies there is no warranty or service. Sound is ok butI don't recommend at all. I suggest buying products from reliable brands from your local shops with warranty and support, even if you have to paid a bit extra, peace of mine is more valuable than a few dollars.
Nonsense, I have this speaker for over a year. Fine sound and quality. Only issue that I have is that it looks for the latest device that was attached to it’s bluetooth and not to the most nearby device.
