I was a little dubious about trying these but they've been so long lasting and look great - I clip and file mine to my preferred shape.
My one tiny niggle is the the clear adhesive patches are a faff to get to stay on my nails as I peel the lasting backing off but I use the nail glue as well for extra strength.
Poor the light does nothing and had to send back one set of nails for the second set to be just as bad.
I used to get gel nails done every 2 weeks, have tried so many at home options and the gel strips are definitely the best. Last a long time, don't damage my nails. V pleased
