I was a bit dubious about ordering this product due to mixed reviews online. I am a novice when it comes to doing shellac nails, however figured for the price of a few salon shellac polishes I could do my own. I have had 2 cnd brand shellac polishes done at a salon. The first peeled after 4 days the 2nd lasted 2 weeks and I removed it due to the regrowth rather than any chipping. I ordered the bluesky shellac to test value for money and so far I am really pleased with result. I used the base coat then cured for 10 seconds 3 thin coats of bluesky dark lava colour each cured 2 mins then the top coat also cured under UV for 2 mins. Wiped off with alcohol UV wipe to remove the tacky layer and was left with a perfect shellac polish. The finish is shiny and hard and the colour even. I have had the polish on for 2 days and so far no sign of any deterioration in the tips. I have had no adverse reactions and I am so pleased with the result. I have ordered more colours and will just monitor to see how long the polish lasts.
