I dont have that one, but I hear great things about it! I think the g4s are a good line with powerful rumbly vibes! For the most vrooms you should look at the wands. I have 3 that I love! There is no way a battery operated toy can give you as much power as a plug in wand. I like having them for those days when my other toys just don't have enough oomph, or I just want to climax quickly. Take a look at the wahl 2 speed
, the hitachi
and the inspire
. They all have pros and cons, but I end up using the inspire the most as I like being able to control the level of power and I like washing the detachable silicone head.
