It feels cheaply made but it looks like any common fitness watch. More importantly, it captures crystal clear sound recordings for hours and hours on a single charge. The advertised battery life of 24 hours seems accurate. I had to surreptitiously record several sessions at a multi-day business conference and it did not fail once.
