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🤢

Bitterness that lingers. Amazing product!
I’ve tried bitter nail-biting deterrents my whole life, and none of them worked like this one. The first time I went to bite my nails, the taste stopped me instantly. It is extremely bitter. honestly awful, but in the best way! The flavor spreads across your mouth and lingers unless you rinse it out, which makes biting your nails impossible and memorable to not do it again. There’s no smell, no sticky feeling, and it feels natural on the nails. I also love the name “Strong Will.” Every time I use it, it reminds me that I do have control over my habits, especially with the right tools. This product works exactly as intended. Highly recommend.

Effective but strong!!
I've been a biter since I was a kid... nails, cuticles, the finger flesh itself --- I'm in my 40s now and I swear by this stuff. I've bought it 4 or 5 times now. Admittedly, I'm not consistent in my application of it so one pen lasts me at least 4 months. Also, it hasn't broken the habit in that I still bite my fingers without it, but not as much. I apply quite a lot at one time. I click about 3-4 times until I see the liquid visibly on the brush tip and apply it to the end of each finger. I only have to apply it every 2-3 days as I can taste it after washing hands several times, taking a shower, washing dishes. It does dry out my fingers a bit, but I just add cuticle cream or a tiny bit of hand lotion to combat that. I'd say the only downside for me is that any finger foods can end up tasting like it if you're not careful and if you tend to lick sauce or something off your fingers, don't!
