Quality expected at the rendezvous. Although there are other lower cost brands with good value for money Opi remains easy to apply. It still remains a bit pricey considering we remade the gel every 3 weeks / 1 month. I'm not sure just buy because I do not find this essential quality. Nevertheless I recommend especially for fans of Opi! Dries in about 45s under a UV lamp. I have not finished the bottles so no notion of the number of use.
