My service here has been very mixed. I dislike the fact they claim to do bio-gels when really they are using acrylic. Bio-Gel is never in a powder form and I told them this and I questioned them about it they said no they were gel and charged me for gel. I since haven't returned and go down the street to urban nails where I can get genuine bio-gel and not be overcharged.
I find M Nails is good for regular mani - pedi and so I have given them a 3 star rating. M nails is also a very clean nail salon and so they deserve a 3 star rating for that!
