I'm confused - are you asking about pocket rockets or fairy vibes? Because a pocket fairy is not the same and a pocket rocket . A pocket fairy is a small version of a wand and its barely 4 vrooms not 5 I just got one- but it is USB powered. It has a round head and is very buzzy. Even the pocket version is a lot bigger than a pocket rocket . Pocket rockets are even more discreet. They are about 3 inches long with a flat head with 3 metal bumps and often have interchangeable caps. They are generally fairly weak but if you can find one with more than 3 vrooms they are worth investing in as they are versatile and discreet .
