I don't know where to start!first time I went here I got full set acrylics and after about a week 2 nails had fallen off. It was during Xmas season and was a huge inconvenience as everywhere was shut and couldn't fix my nail until after Boxing Day! I then went somewhere else in Finchley and my nails lasted 3 weeks after which I went back to USA nails for infills and yet again after a week nails falling off. I visited again last Thursday and had infills done and 3 hours later half of one nail broke and I had to go back on Monday!! All I got was attitude and the nail technicians speaking in their own language telling me I should have got shellac!!! I explained I have got acrylics many times and never has one just fallen off after 1 day!!! It is now Thursday and the nail on my pinky just fell off. I am fed up and do not want to visit again even to fix it. I don't know what kind of bad out of date powder they use but it doesn't last. AVOID THIS PLACE AT ALL COSTS!!!!!!!!!!!!!!
