I bought this the CL 2 with the idea that it would be like a vibrator in the traditional sense aka a battery powered ******. Just like vibrators that women can buy. It isn't like that. It only has enough room for the head and a little shaft. So, if you are considering this toy, don't think that you are going to be able to come home and **** it like a ***** every night and have an explosive ******. This is more a ************ aid than a fake *****. I am using mine right now as I am writing this. It feels great. There are several vibratory settings (16 I think). You can hold it or lay it in your lap and just let it massage the head. It has a USB charging hook-up that is very unique. The initial charge takes 16 hours, but then it keeps its charge for a long time. it actually looks like a computer mouse, so for you brave guys out there you could take it to work or put it in your computer bag when traveling. Its made in Germany, so it is built to last. Buy it, charge it and sit back and let it melt the stress away.
