## Customer Reviews

### ⭐⭐⭐⭐⭐ Working fine
*by A***A on 2 June 2024*

Bought it for repairing my bluetooth speaker. Bluetooth range is very good. There is sound distortion on high volume but it is very easy to install (just plug in speaker)I have used 2X 5W 2Ohm speaker, it works without battery connection also and at starting and connection does not make that annoying "bluetooth device connected" sound, it is just a ting sound.There is led also on chip.Total value for money, even though i have seen it cheaper at some places but delivery time and courier charges are very high so no point.
