Great amplifier board! The Bluetooth 5.0 connection is super stable, no dropouts even when I'm 10 meters away. The Sinilink APP control is really convenient, I can adjust volume and switch songs directly from my phone. I used it to build a portable outdoor speaker, and the 100W×2 output is more than enough for backyard parties. Sound is clear with no distortion at high volumes. Installation was straightforward, all ports are clearly labeled. Highly recommend!
