This is a great nail strengthener and has saved my nails! CND are great nail products. The parcel unfortunately went missing after delivery was left on the doorstep and not in the safe place. CND sent a replacement promptly, you can’t ask for a better service of a great product.

Very happy how quickly it was delivered and I have only been using it a week but do feel my nails do feel a bit stronger so roll on a few more weeks and hopefully have nice nails.

I had builder gel removed badly and I'm left with very paper thin nails. No choice but to grow them out. Although this does strengthen my nails it's not enough and I'm concerned with the nails being so thin the chemicals could damage the nail bed. I will definately use this once the over filed grows out hence 5 stars.
