The instructions are easy to follow, but mine still caught on stray hairs and once those things start lifting, that's it. Two days is all they lasted for three nails.
Whilst they tried to be helpful, I had warmed the gels up.
Fortunately they are easy to remove.
Unfortunately, their email saying I had a subscription went into spam so I've now got more wraps on the way which I didn't want. Their customer services are friendly enough but if you expect these to last two weeks and you use your hands a lot, then don't bother.
