This is exactly what we were missing in our home. Someone around here is usually playing songs on their cell phone, and it drains the batteries. This speaker's ability to sync up in the bathroom during showers, in the gym during workouts, and in the garage during weekend projects speaks highy of it's utility. It has a non-slip surface which means we can put it on various surfaces without incident. The volume gets pretty loud, and I love the ability to take phone calls. This allows me to keep my phone charged while I'm doing other things. Highly recommend!
