Review title is Unsuccessful [SEP] The brush on the double duty gel is cut wrong, it has a chunk missing in the middle, making it impossible to get smooth, all-over coverage which messes up the entire process. I’ve been unsuccessful in getting a good application. And the second time I tried to open the gel it was sealed shut. Once I pried it open it’s too gooped up to use. I bought this kit to give revel a try before buying a full kit and I can’t say I could bring myself to risk spending $45 on a full kit.
