I normally like Apres products, but this is a dud if you are doing your own nails or are a leftie. I contacted them before purchaching and they told me that this bit was two way rotation. They seemed baffled, in fact, by what I meant (???). It means that for left handed users and/or if you're working on yourself with your non-dominant hand the cuts in the ceramic are sharp in either rotation (forward when you are moving counterclockwise or reverse when you are moving clockwise- usually lefties or when doing your non dominant hand). I've been doing nails a long, long time and was excited and ordered it immediately because two way rotation is not common in ceramic bits and certainly not ceramic cuticle bits (cone or flame). I experimented right out of the box and found that it is exactly like other brands that are forward rotation only (clockwise) and the friction only works well when running it right to left, just like all the others on the market (I've since found Grandado are they ARE two way rotation). There is some friction when running it backwards but not nearly what is needed for it's purpose (in my case, sealing the cuticle after gel x application). Waste of money.
