This product is excellent it is the only one that improves my peeling nails.

Good 06/05/15

I've only been using this a couple of weeks and so far so good. If it improves my nails which have been weak and splitting for years, I will give it an 'Excellent' next time I order.

Good product but it seems as though the Dr LeWinn's oil is no longer sold seperately

I've been using Renunail Strengthener for 3 weeks now and can see & feel a significant improvement in my nails.

Excellent 06/03/15

Discovered this a few years ago and it's the only strengther that works for me.

Poor 21/02/15

It did nothing to improve my nails. I've used it according to instructions for four weeks and now have to have a week or two without it before having another four week stint. My nails are as bad as ever, no improvement at all. It's over two years since I last had acrylics and moisturise my hands regularly.

Excellent 19/02/15
