I definitely recommend this toy to the avid vibe user looking for an update to their collection without shelling out a ton of cash. It's strong vibes and big size make this toy better than the typical Pocket Rocket, but not so complex that it takes away from its intended job. If you can overlook the funky battery construction problems, definitely check this toy out.

Oh, you said hard on...
If you want to give someone a vibrator for Valentine's Day with hearts on it or you want something abrasive, hard, and huge this is an option. This is not a good choice for an everyday use vibe. I would not recommend this for beginners or if you are looking for an only toy to get your collection started with.
