This product was very disappointing, although it did what was advertised, it just did it very poorly.
Rubber sleeve is well made however I found the build quality to be very low, the buttons were very clunky, the vibration was weak, and I’m not even sure it sucks!
Needless to say it’s gone to landfill.
Have had multiple masturbators and a few hands free. This by a LONG margin is the greatest I have ever purchased. FYI if you're on the girthy side it may not be for you.
