Working fine
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.

Pricey but reliable and easy to install. Boom boom.
Repaired my f&d 200 sound bar as the inbuilt amplifier was busted. Didnt install the battery rather kept a usb cable for power input. Will recommend to everyone. The bluetooth range is approx 20-25 mtrs and realy crisp sound.

Connectivity is fast... But little laggy when there is only speech... Gap between silent and voice, and first word will be half heard.... Amplifier is good... Base o dono, bcz i have installed to 9W speaker...

No Power on switch
Why this does not have a power on switch.After stop using it will go into standby mode.Cannot use again unless the battery is disconnected for 2 minutes and connect again to go into paring mode.THIS IS BAD.

Efficient and noise free Bluetooth reception and compact PCB
The media could not be loaded. I have used 7805 volt regulator to feed this board power from a 12 volt 3AMP PS. Installation is easy however, the polarity is wrongly wired (for me red is -ve and black is +ve) therefore, go as per PCB mark only. I've fed this board as audio input to STK 4141 power Amp board which could create some distortion but it served the purpose for me. I did not understand though why there is static in every pause or change in song while playing through this bluetooth board. The issue is in all the cases and does not happen If I play song without bluetooth through the same amplifier.

Don’t buy this product. Waste of money.
I bought this product for diy speaker project but it overheats under 30s of playing music. Even on recommended speakers and charge. Not worth buying.
