Great product
This is the only product that helped me grow my natural nails. The bitter taste is absolutely horrible and there was no way I could bite my nails.

Perfect
I’ve been biting my nails since I was 7 years old. I take medication for anxiety, and I’ve tried using fake nails, but since I didn’t have a proper base to stick them on, the glue caused an allergic reaction. My fingers became itchy and developed pus, so I didn’t know what else to do.This is the first time my nails have grown long enough to reach the tips of my fingers. This product, despite being unpleasant, works amazingly well. Even after washing my hands multiple times a day, taking showers, and scrubbing my hair with shampoo and conditioner, the product stays on. It’s incredibly bitter—very, very bitter. The smell is typical for nail polish.I absolutely loved this product

Working my way to stopping torturing my fingers
I have had this nail biting problem since I was 3 years old, picked it up from my mother.. I have tried a similar product when I was little, but now, as I am getting into a world of careers, I am determined to quit it more than ever before. All my efforts were useless, so, after doing some research on this kind of products, I bought this. The taste is really awful and stays for quite a while. I am applying it every 4-5 days, and my nails really got longer after the first two weeks! I go swimming on a pool occasionally, and the chloride in the water eats the taste off, so it's not a good idea to apply it before going swimming. Other than that, I am definitely going to go on using it . Excellent product, reminds me of wanting to love my nails and have them pretty every time I forget about it myself ;)

Extremely effective
This product has really helped me. I have been a nail/skin biter my entire life and it's a disgusting habit I've always wanted to change but found difficult as I bit my nails as a coping mechanism.As soon as I started using this product from day one I completely stopped. The taste is so bitter it really does put you off putting your finger anywhere near your mouth. The bottle is small but lasts a very long time as you only need to really apply it once every 4 days or so and even a small amount per nail will work.It does have a couple of downsides but easy to deal with. First is that I'm a man and it does make your nails a little shiny which is embarrassing but if you apply it the night before it should dull while you sleep and be more discreet. Secondly if you cook or eat with your hands you will get the taste on the food/in your mouth so make sure to use utensils where you can or get (disposable) gloves that are suitable for food handling.Overall though I still give the product full 5* since it is very effective at what it's advertised to do.

It works!!
I brought this as I have 2 nail biting children and was at my wits end.1 month later both are no longer biting, we have some good growth and I am hoping we have cracked the habit for good.100% recommend.

Works like magic
I only had to apply it twice on my 3 year old and that was it, no more sucking. Unfortunately that wasn't the case for the 5 year old, she carried on sucking away and I had to use an alternative method. So whether it works or not really depends on the child's taste buds and what tastes they prefer. The 3 year old generally likes sweet whereas the 5 year old likes salty and savoury.

Awful taste, but my 3 year old manage to overcome this within a day
We have tried one other product and had some success with it, but then something happened in nursery and my 3 year old decided that she will go back to sucking her thumb. We left it a while and then tried this product. Its clear that the taste is awful, but it doesnt last as long for us as for other people (we had to apply it twice a day to have any effect). My daughter however quickly realised that if she sucks her thumb and doesnt swallow the saliva, she doesnt feel the awful taste. So she spits it out and puts her thumb back in :( I would definitelly give this product a shot if you are trying to stop nail biting/ thumb sucking.
