Came on time and does what it’s meant to. Works great like an acrylic almost eg. use a tip and use poly gel to create base before painting on gel. Had some started up issues as when I went to put on the poly gel it didn’t come off my nail but that could have been cos I used improper tools so I reccomend buying the full kit.
