Dr Lewinn's Renunail - has anyone tried this?

[kikidee]

I have seen this advertised and read some glowing online reviews but just wondered if anyone had tried it and had anything, good or bad, to say about it. I have very badly splitting and peeling nails which OPI Nail Envy is not helping so would like to try something else if it really works. Thank you.

I've used this and have found it brilliant. I notice a difference after about 3 days and my nails go on to grow without breaking or flaking. The only problem I've had is that the last third of the bottle tends to go gloopy and then it doesn't dry/set properly and isn't as effective.

Love it! It's quite expensive though, I've not found anywhere that really does it significantly cheaper than anywhere else.
