I really liked this topcoat. I purchased at London Drugs for 10$ CND and am really impressed with what I go. It is a smaller bottle but for 10$, that is what I had anticipated. It was just like other gel topcoat, use LED/UV and wipe. I have had it on for 6 days and still have it on my nails. The better you seal the better it lasts but overall I am very impressed. It stays super shiny and doesn't have any overwhelming odors like some gel polishes. Overall I recommend and I am going to try their gel polish color line also .
