Hotorda Wartenburg Neuro Pinwheel Stainless Steel Diagnostic Instrument Pinwheel Pin Wheel Gear Roller Rolling for Testing Nerve Sensitivity. 1 Round

It is good quality and comes with replacement wheel.good price

After reading the reviews I found out this device has... alternative uses, or maybe my use is alternative. However, it does a good job at scoring material.

Beau petit outil pour apporter des sensations plaisantes et agréable sur tout le corps! Pour mettre un peu de piquant au lit et c'est le cas de le dire! Je l'aime bien!

We are not doctors:My husband is in constant pain. He uses the pinwheel to distract the brain by running it across the skin, on a different part of the body, "Defering the pain". He says it may be fleeting, but any respite is welcome. It is easy to use and we'll worth the money.

**my review is for people using this in bedroom sports**My only complaint about this particular wheel is that it isn't sharp at all, which makes for a good beginner tool. It's great for experimenting to see if you like it. It is a little bit noisy but that didn't bother me. The cost is good for what you're getting, and it gets the job done if you want to try it out. I personally would want it to be sharper. It fits in the hand nicely, and is easy to use.
