I have been using Artistic Nail Design's LED-cured "Correction Gel" (the one in the pot) for a couple months. I also now own the brush-on, thinner, version but have yet to use it. I ordered the hard-gel version as well, and it is sitting in my shop, awaiting some one-on-one training (the lovely Christina Gonzales-Glennon, educator for AND, will be giving me some tips & tricks on September 9th). Once I have tested out all three of these gels, I will be posting a review for you. Stay tuned!
