Finally a product that works
I had tried so many things for my 6 years old to stop sucking her thumb at night ( dr thumb, thumb guard…) only this is working!

100% works
My son is a anxiety nail bitter and also special needs and we had tried everything else out there to help to stop biting and let me tell you this stuff works!!! Unfortunately I can not find it to buy it again so he has gone back to biting. I needed up getting some on my finger without knowing and yup definitely nasty tasting🤢

It worked!
Our 4yr old child resisted every possible intervention for his finger sucking - positive reinforcement, hot sauce, a different bitter product, finger guards, arm braces that wouldn't let his arms bend. He overcame them all. Then as a last resort we tried this beautifully bitter anti-nail biting click pen. It worked and it worked really, really well! The solution is bitter and it tastes bad (not as terrible as I thought - it didn't make me or my kids gag), BUT it doesn't get all over everything which means it was very effective at preventing finger sucking, but didn't interfere with eating. It doesn't wash off easily, but will fade over the course of the day which is a huge plus in my book. We applied it 2x a day just on the nails of the fingers he sucks (after breakfast and at night), and in about a week our child didn't reflexively try to suck his fingers all day long. A week after that we were forgetting to apply it and he was not attempting to finger suck unless napping or sleeping. About 3 weeks into it, we are now down to just nights and we probably don't even need to do that. We have not noticed any peeling skin as reported in other reviews. This product changed our life and our child is so proud of himself for breaking the habit! I'm so glad we found it! We did try a different bitter product over a year ago and it was way too strong and the bitter taste would transfer to everything. Nail Quail is a far superior product and our kids daycare said they could keep it in the class given the natural ingredients. Day care has never had to use it - it's presence is enough of a deterrent.

Really works
Works well but also have to set your mind to making it work. The taste is horrendous if you attempt to bite your nails but I have heard some people are determined or have such an addiction to biting that they can overcome this terrible taste. Not me. It worked for me.
