The process is a lot trickier than the adverts let on and even when following the instructions (which takes ages and is not easy, it’s easier to paint gel and cure x100) it doesn’t last as long as gels, if you moisturise your hands they lift straight away
Also be careful they sign you up to a subscription under the guise of a reduced price but very quickly take the next payment and even when asked to cancel the order (before shipment) they refused and kept the money. Bit of a dodgy insta scam product.
