I wanted a small Bluetooth amplifier for my work shop and bought some cheap TDA7492P bare-board versions from Ebay. Luckily there is other good Bluetooth amplifiers!
This poor TDA7492P design is over-advertised and abused enough that I requested my money returned from the seller.

Not a paid review, bought for my own money and independant rant! I can only hope this will turn up in peoples search results if looking into buying this kit.
