I have had the original Miatone speaker for over a year now with absolutely no issues. Okay, so I ordered this 3 1/2 years ago and am literally just now getting a chance to use it. Other then that GREAT QUALITY SHOE. The sound was terrible in general. The 2 parts don’t impact around the hinge which to me shows the level of design Monocarbon put into it. Update: 7 Months later and these are still operating great like the day I received them, and still on the same set of batteries. Every time I lock my computer the mouse just resets the settings and starts cycling colours as if I just plugged the mouse in first time from the box. I was worried they would be to small, but no. nd experience is pretty amazing. I thought I could try and like the dry shampoo.
