The Charm O vibrator is a 6 3/4 inch long, silicone covered, multi-speed vibrator.
The vibrations are very deep and rumbly, and the rumbles radiate out to the special "O" ring at the tip of the vibrator.

The Charm O takes two AA batteries. Depending on your length of use, this could last up to 3/4 play sessions, at least for me anyway. I have used this for about 2 weeks every single night, and so far I have gone through a handful of batteries.

This toy is covered in a silicone coating, so using silicone lube with this toy is not suggested. To clean it you could use any toy cleaner, or some good old-fashioned soap and water!

This toy is waterproof, but not for submersion! Take it in the shower, or wash it down in the sink after use, but don't use it in the tub since it cannot be guaranteed to work after being submerged like that.

The dial base on the toy is very easy to operate and offers multi-speed vibrations depending on your preference.

As I mentioned before the vibrations that the Charm O produces are deep and rumbly, so if that's your preference, then this toy is for you! The ring at the tip of the toy offered a great amount of vibrations and fit well over the clitoris. This toy is oddly-shaped because of the ring at the tip, therefore it did not feel very good while inserted. This may be different for everyone, but I did not personally care for the feeling when it was inserted.

The Charm O came in a plastic formed package that had a picture and description of the toy, as well as a place for the toy to fit in it. This was not a discreet package at all. The package was also very hard to open, and required scissors or a knife!

My personal experience with this toy was good. It offered great vibrations for the size of toy that it is.
The ring did work as it says it did, and it provided strong vibrations to the clitoris, which is the point, right?
