I have used both OPI Nail Envy and this strengthener and this strengthener works just as well and saves some money.

I have, and I prefer this product. They are on the same level as far as strengthening goes (Naily Envy really is fab) but I give this one the edge because of price-point.

This does not have Formaldyhyde in it, which Nail Envy does (I think the orange label does not have it). I have not noticed a difference in my nails with the Nail Envy, PLUS, you have to repeat it every other day for a week. With this Nail Strengthener by OPI, I feel like my nails stay smoother after I take it off. My opinion, it doesn't take too long to dry. I don't know why OPI says they're 3 free, because they are not completely 3 free with the Nail Envy (false advertising-which I guess every company does), but I didn't notice any difference (other than the Nail Envy is a pain in the butt to apply!).

i am a big fan of nail envy and this seems to be about as good. it doesn't dry as quickly and is a little glossier than the original, but otherwise it feels like it gives strength to my nails. one thing i didn't adore about nail envy is that it yellowed within a few days. this seems not to have that issue.

I like Sephora better than nail envy...maybe just because I've used it more. It doesn't seem as strong.
