Finally I have beautiful nails for more than a week: The instructions are easy to follow. It takes about have an hour altogether. As the nailpolish bonds only under the light you can take your time to put it on! I never use Acetone to take them off. After let's say doing dishes in hot water or soaking them in it - they easily peel off after they had been on for maybe a week or even more. And there's a special tool you can buy that helps peeling them off. And I do not buff the nails as they are already rough enough after having peeled off the old ones. Usually I take a one day break where I pamper the nails with oils and cream before putting on the new layer. For me it's just the best - worth every penny :-)!!!

Bought two cases to try and ended up using this one for my own IPhone 6 Plus (pink one was for wife's IPhone 7 plus). Works perfectly fine and offers the protection and minimalistic look that I was looking for.
