A little practice can make this juggling act perfect!I really like this toy. It's different than the usually pin-pointed vibes out there. Although you can't get that pin-pointed vibration that some like, you can apply firm pressure, which may not get you there immediately, but will be so rewarding once you "arrive".
That said, I am glad that the toy is also quiet. I use it alot and this is part of the reason why. The vibrations aren't super strong, but the sound is also that that loud. Seems like a fair exchange for me. The waterproof ring seems to work wonderfully. I've never had any issues. It does seem to chug battery life, but I use rechargeable batteries, so this doesn't bother me too much.
I store mine in the box that it came in. It's easy to roll about and the box at least stabilizes it. I wouldn't store it next to another toy, just to be safe. The TPR could react and you might end up with a bad or sad situation on your hands.
It may seem like more trouble than it is worth to use this, but I find it to be a lot of fun. It is different and feels different than the usual vibrators I have. It’s fun to change things up once in awhile!
