The only bad thing I can think of is the Bottle is half empty, & im about to run out! Works well for the backing of my Class B motorhome! Bass is 9/10, but otherwise quite amazing. Perfekt ???? 5M because my feet are wide. Setup was easy and squaring it to the table was extremely easy as well. Buying a hub for a Thunderbolt USB-C laptop is like the story of goldilocks, with Docks/hubs that are too big, too expensive, and eventually, you find the right balance. The Bluetooth controls rock to the volume is controlled by your device so you can definitely drowned out the music if you need to. 6 days later it is now tearing at the hinge point that joins the body to the lid. Then I put the original sole back in ontop.
