This vibrator works well and has good battery life (user info says 1.5 hours depending on power setting). It's not very powerful, so if you're looking for a deep-penetrating neck/back massager, I'd look for something a little more powerful. It has many different vibrations but I've found that I don't like any of them other than the usual constant/consistent vibration. Different speed settings are good. I like the silicone material. It's soft and smooth, but smells quite strongly of paint. I've had to wash it with soap many times, but it still has a slight paint/chemical smell. It's waterproof, but I wouldn't recommend submerging it in water. The only hole for water to get in is on the bottle itself, where you plug in the charger, but it has a silicone gasket that seals it. It's easy to use in the dark because when it's on, the settings buttons light up, as you can see in my attached photo. I have also included a photo of the user manual/care instructions. This vibrator is good for the price but I wish I could use something stronger, it doesn't give my back and shoulders the relief I was looking for.
