The packaging on this one is a little flimsy but the product its self is quite nice.
The double wheel gives a good surface area and means that it moves very smoothly against curves. It's a nice sensation but not too sharp on the skin, thought you could probably get some variation based on how much pressure you put in.
Definitely have somewhere secure to keep it because it will be the type of thing that picks up hair and other lint if left out. And definitely be careful about where you put it down. I think it could be much less pleasant if someone accidentally stood or rolled on it.
Really fun little product. Depending on the pressure applied it can range from a nice, back scratch type sensation to an intense, painful one. Great for driving a partner wild.
The plastic handle does feel slightly cheap, but for the price, it is very good value. The duel heads also allow for good contact while running it over the curves of someone's body.
Would recommend for anyone wanting to start exploring as well as experience users looking for a good value extra for the tool box
