I purchased a set of nails and the starter pack which included the lamp, removal solution and top coat. I never got as far as using the top coat or removal solution as I couldn't get the nails to adhere. They were so thick and inflexible that they didn't stretch, or bend to the curve if my nails. Also the adhesive lost its stickiness immediately if they were even lightly touched. Followed all instructions including the videos. After curing them 3 x the nails were no harder than prior to curing them and pulled off very easily. 100% would not recommend buying this product.
