I LOVE this. I have very weak nails and normally cannot grow them more than a millimetre or so long but since using this I have nice long nails. No lifting, no chipping AT ALL. I am not a professional and apply this myself DIY using an electric file and my tiny LED light which works absolutely fine. Pictures show how easy it is to get a nice finish (I'm typically rubbish at doing my nails). Left hand not the best but good enough for a DIY attempt. Highly recommended and great price. Also arrived incredibly quickly - great service.
