1. they are easy to use2. BUT they are not as dark as the picture and the DP color is not like that its a light color smaller glitter but that will not keep me from using it3. this is only the gel ! you will need tools, forms, base coat, primer , top coat and nail clips and lamp i will update on how long they last you do not need a drill to file them downi would have given a full 5 star if they was the same color as shown
