Rated 3 out of 5 by from Sadly disappointed in the new formula I have used the original Nail Envy and Nail Envy Matte for over 20 years and my nails have been amazing as a result. I'm devastated that both, especially the Matte version, have been changed. The so-called improvement does not work: it chips easily and does not give my nails the armour coating the orignal products were so good at. My nails have suffered and I sadly have to look elsewhere for a replacement so I do not have to resort to acrylic or gel nails to maintain good looking nails. I wish OPI would give the customer the option of the tried and trusted recipe or the new vegan recipe.

Rated 5 out of 5 by from Actually works. Well blow me down, this does actually do what it says it will! I put it on for 6 days, and by the end -actually by Day 4 - my nails stopped flaking. Before, they would separate into layers at the tip, and the top layer flake off, and then the other layers too. Now it all stays together. Sadly my nails still break off, just without flaking first. So I'm combining it with another brand's Nourishing Nail Pen, which helps. NB You need to put oil on nails when using OPI's stuff because it's quite drying, my nails looked dry and ridged by Day 6. But oil sorted that.

Rated 2 out of 5 by from Not for me. After prolonged shaking the colour is difficult to apply evenly , it does not cover well and appears stripy. After five coats it still doesn’t look right. In retrospect I should have stuck with the original clear Nail Envy

Rated 2 out of 5 by from Stick to what you know. A very disappointing purchase. Having used the original Nail Envy with success I decided to replace it with a colour. I shouldn’t have bothered, I find this difficult to apply, the coverage is very poor even after several coats.

Rated 3 out of 5 by from Still hoping Haven’t seen much of an improvement yet, my nails go through fazes and at the moment they are pealing the layers.
