My hard gel extensions started lifting up at the edges within a week. The technique involved using soft gel on the back of a nail form to shape the extension, but the nail form did not fit my nail perfectly and was too thick at the edges, hence the lifting. Not enough attention to detail, shaping at the cuticle, edges or back of the nail was done. Considering the price this is not acceptable. Two stars because the polish was nice. I won’t be back.
