The only negative thing is that it has a startup sound signal which cannot be deactivated or I cannot find instructions on how to do it, and the volume adjustment is a bit strange (the potentiometer does not respond to 100%). However, it is not a major issue.

Definition of vfm!!! Crystal clear sound!! Connected to 2 passive speakers with input power 36watt / each and supports them perfectly. Instant Bluetooth connection without any distortion. The only negatives are the flashy colorful Chinese appearance, the 3-month warranty, and the fake remote control that probably won't last long. However, for this price and having a remote control, it is impressive since you don't even need it for Bluetooth use. I haven't used the mic inputs in case someone buys it for karaoke use, which is the target audience for this particular model.
