Shellac itself is good except I have noticed a few blobs where I just have knocked the drier that the therapist didn't notice, but I can deal with that. What I can't deal with is having someone handling my nails with a cold, blowing her nose and coughing without using antibacterial gel afterwards. I have now caught her illness, totally unhygienic to have someone working with nails when they're sick, needless to say I wouldn't recommend this place!
