Just after some opinions as this is the only gel polish I've used. It seems quite easy to apply, I've done it for several friends and my sisters and on myself lots. It seems to last and last and had loads of great feedback on how pleased my sisters and friends were with it and how long it lasted. I've actually had more trouble trying to get the stuff off! It's like welded to my nails so no chance of chipping or peeling. Was thinking of converting to shellac though as this seems to be the one everyone raves about. Is this like the gold standard? What does everyone else use? Also to do the conversion course it says about buying a shellac lamp. I already have s £90 led lamp, will I really need another one?
