this just doesn't want to cure for me! [SEP] I have a small collection of gel polishes. Most of them cure fine with 90 sec on each coat. I have cured this one for 180 and I cannot seem to get it to set fully through. The polish is thick going on and I guess the light can't reach? I don't know. Inevitably, I think I'm done and i rub a nail the wrong way and it slides, revealing uncured black polish underneath.  I won't be ordering this brand again.
