Q & As

Rated 4.7 out of 5 by 6 reviewers.
Rated 4 out of 5 by useful aid to stop nail biting I have bought this for years for my husband - it has not stopped him but it reduces it to a manageable level and it is the only product like this that he finds useful. 04 February 2015
Rated 5 out of 5 by Strength without being brittle Highly recommend! For the first time in years I have long nails. 27 January 2015
Rated 5 out of 5 by Product worked for my daughter Used product on my daughter for just 5 days. She has stopped biting nails now. 02 September 2014
Rated 5 out of 5 by Brilliant This is the only thing that stops my daughter sucking her finger! It really does taste disgusting yet is easy to apply and quick to dry - just like a clear nail varnish so suitable for school. 23 July 2014
Rated 5 out of 5 by Tastes vile - perfect! Works very effectively. My 6 year old has now stopped biting his nails. The taste is truly awful and lingers. Seems to better than the Stop n Gro variety 19 November 2012
Rated 4 out of 5 by Excellent product If you want to improve the condition of your nails, this is the product. The nasty taste of the polish means that you'll think twice before biting your nails again. 08 February 2012
