### ⭐⭐⭐⭐⭐ More than expected
*by D***. on August 3, 2023*

Really love this product. It is capable of a lot and has everything you need to get it bumping right away. Sound is crisp and it does not even heat up. The only downside is that in order for the Bluetooth to be fully disconnected, you have to disconnect the device from the power. Even if it's off, it will still be connected to the Bluetooth.
