This vibrator is meant to be worn on the tongue during oral sex to provide some vibrations to the experience. It is tiny and easy to throw in a purse of maybe even a pocket to take with you to be prepared no matter where you go. I thought this would be a great toy however it was a let down. The ring is so stretchy it can also double as a cock ring.

The Tongue Dinger is made out of TPR Silicone, which rates a 6 on the safety scale. There is a slight smell but it is not at all noticeable unless you practically shove it in your nostril. There is no taste which is a good thing since it is meant to be in your mouth during use.
The inside of the ring has little teeth along the inside with 2 balls on the bottom where it would be under your tongue. The part that rests on top of your tongue has little nubs. I'm guessing they are meant to help hold it in place. On the opposite side (the side for stimulation) has a raised spot covered in nubs and 3 raised ridges.

The design was flawed in the sense that it failed to even stay on the tongue no matter how many times I tried to put it on. It was much too bulky to not get knocked around when performing oral sex. It is supposed to stay on the tongue but the material is so slippery that it just keeps slipping right off. It is only 1.25 inches long and so is easy to hide and take anywhere with you.

The Tongue Dinger really only functions as described in the way that it does vibrate, however it does not successfully function on the tongue as it is described to. In the same way it does not perfom the task it is said to perform since it wont stay on the tongue. When turned on there is a buzzing noise but you wouldn't be able to hear it through a closed door, but you wouldn't get away with use in public. This toy is waterproof and properly vibrates when under water.

The Tongue Dinger is labeled for single use with 40minutes of vibrations to be expected. However when we were done with it there was still battery power left, in fact we have tried it multiple times and there is still power left in the battery. Since this toy is labeled for single use you may not need to clean it if you use it up, however if you get multiple uses out of it you should clean it. First remove the little bullet from its sleeve. Then since it is made of TPR Silicone you should wash it with warm water and soap or antibacterial toy cleaner. The TPR Silicone also means the Tongue Dinger should only be used with water based lubricants.

This was definately a let down from what we were hoping for. We would definately not spend our money on this again nor would we suggest it to anyone else.
