While most toys of this style aren't very powerful, this one does a good job for its size. It has surprisingly powerful vibrations and the dolphin's nose helps to effectively transfer the energy. Although, if it had bumps on the nose that would make it work even better. My girlfriend enjoyed it, although there was a defect in the cord going to the control box which caused it not to work properly (it kept cutting off). Luck of the draw I suppose, but thankfully the return policy is great. I'm sure that was an isolated incident and the next one will be fine.

Although the toy was not quite as powerful as would be needed to fully get my girlfriend off (however, she requires a lot of vrooms so to speak; our current favorite toy being a Hitachi magic wand). Considering strap on toys just don't come that strong, we found another great use for this one. It works wonderfully to tease and it's fun to have someone wear it under their clothing for an extended amount of time to constantly tease them. The longer it goes on, the better. My girlfriend and both love this idea and intend to explore it further when we get one that works properly.

The straps that hold this product on are very adjustable, so they will fit a wide range of people. They are comfortable and easy to put on. They seem to hold it in place fairly well too. The toy's material was really soft and we found it to be easy to clean.

Overall this is a very fun toy that is well worth the money and has many uses. Given that my girlfriend is submissive, we found the most fun in bondage/teasing situations, but it does a good job overall.
