I tried this on my tongue and my finger. I have to say while it looks small it is kind of big in a mouth which may make sucking dick a little challenge for smaller mouths. You can always put it on like a ring and give a hand job. The nice thing about it is that it is smaller and can be brought with you as an added sexy surprise for the night.

The dinger is made of TPR silicone so it is a safe material to use. Since it is a type of silicone, I suggest only using it with a water based lube. You should wash it with warm soapy water before you use it. The good thing is, it was made for one use so you can just toss it when you are done. However, if you decide you like it you can slip the little bullet out and toss that one and then replace it with a "mini" bullet.

The design is great for what it is made for. I had a little bit of a problem keeping it on my tongue though. It does stretch to about a 5.5" circumference. With that being said, you could technically use it around the base of a penis, although it would be tight.

The actual bullet is 1.25" long. There are little nubs on the top of the bullet part and also inside of the tongue part. The ones on the inside of the ring help it grab onto your tongue.

I personally would just throw it in my luggage for any travel. It would fit into your purse, I just don't like that they can see everything that you carry.

The vibrations are a decent strength. They can't be overly strong or you might hurt your tooth! I like that to turn it on all that you have to do is flip the little switch.

The Dinger lasted me about 35 minutes. I was surprised that it even lasted that long. The only down side is that you cannot change the battery. You have to throw it away when you are done with it.

Other than washing it with warm soapy water and thoroughly rinsing before sticking it in your mouth, there is no maintenance. Just throw it away when you are done with it. If you do use it only part of the time and still have battery life left on it and would like to keep it, just wash it and put it away for one last use.

The Tongue Dinger came on a cardboard back with a fitted clear little bubble to hold it onto the backing. It is very simple packaging for a simple toy.
