Review: Fixed my habit of 20ish years!!! - I have an anxiety disorder and have bitten my nails for like 20 years. My nails always look bad, my teeth are damaged, and my fingers are always red and bleeding. I don’t ever really know I’m doing it- it’s completely subconscious! I’ve tried tons of other stuff: I would bite off press ons in 2 days, I managed to make acrylics lift (and subsequently ripped them off and damaged my nails SO bad), I’ve tried wearing gloves, and of course I have tried bitter nail polish. Nothing has worked and I just accepted this was how I was going to live life lol. I’m getting married soon and I decided I wanted to try one more time to fix my habit and bought nail quail as kind of a hail mary. Friends, this is the nastiest most vile tasting stuff ever. I brushed my teeth literally 10 times the first day I had it on. That didn’t help, the taste lingered. I learned VERY quickly to not put my fingers in my mouth. This pen is so unbelievably awful and disgusting that I have nails for the first time ever!!! It is easy to apply and carry with me, but the stuff doesn’t really wash off with basic hand washing so I don’t need to reapply that often (I still do, but). It has no smell and no weird greasy or oily feeling as well as basically zero drying time. It feels just like really disgusting water lol. 100/10 recommend!!!!
Review: 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.

### ⭐⭐⭐⭐ Effective, but not long-lasting
*by C***L on March 8, 2025*

Overall, this is a good product, but having used more traditional nail-polish-type deterrants in the past, I found this to be less effective. I'm giving it four stars due to the application being very convenient and different, but the result was that I ended up biting my nails again more often, as I will explain. I am a lifelong heavy nail biter, and despite using deterrants for 2 years and trying very hard to curb the habit, it's still a challenge. For the last 2 years I used Mavala stop nail polish, which has an intensely bitter taste and is basically a clear bottle of nail polish with bitter chemical added. As long as I keep this nail polish on, I can't bite my nails. Although the polish is water resistant, it wears off in about 2-3 days and by the end of the second day, I may find myself putting my fingers in my mouth some and attempting to bite my nails despite remnants of the bitter polish still being there. This is where these deterrants all hit a snag for me. If I'm not diligent about keeping it on my nails, I go back to biting. Which brings me to the Nail Quail. I bought it to try something different. This product has a similar strong bitter taste, and the applicator is so much more convenient than the nail polish bottle. Initially I was extremely happy with the product because of how much more quickly I could apply it to my nails, and it dries fast too as it is water-based. However, also because it is water-based, I found that within a single day it has already washed almost completely off of my hands (I wash my hands regularly throughout the day, especially when I'm working). To use this effectively, I need to reapply it multiple times each day, instead of ~3 times each week. That doesn't mean it's totally ineffective, but for my case it isn't perfect either. The shape of the product is like a marker, and I think it's meant to be slipped into a pocket or purse to carry around and reapply when out and about. I haven't done this, but I suppose I'll need to start. If I could get a formula of this that was more water resistant with the same applicator tip, I think it would be just about perfect.
