Strong Will Anti-Nail Biting Click Pen, 7ml, Made in USA

My 3 yr old is a thumb sucker since he was 3 months old. We tried a few things like the bitter nail polish(didn’t phase him), the mesh glove(he would break it off), the brace that prevents your elbow from bending(he took it off in 5seconds). Nothing worked. We were worried about his teeth since they were starting to round in the front. My coworker told me about this product and I immediately bought it. Worth a try since it had great reviews. Day 1: He cried after realizing it tasted awful. He kept saying he wanted to suck his thumb. It was awful. I felt bad but he needs to break the habit. Day 2/3: better. I had to trick him to put it on his thumb and whined about wanting to suck his thumb. We are in day 6 and for the last 2-3 days I haven’t heard him whine or try to put it in his mouth. He has put the liquid in his own thumb since he is Mr. Independent lol. So glad its working. I hope his teeth go back but only time will tell.

If you have kids or a certain family member who can't seem to keep their hands out of their mouth you should definitely buy this. My 5-year-old has a habit of biting her nails and getting infections on the side of her cuticles. The same day I put this on she cried and begged me not to put it back on her fingers because the taste was just disgusting. Of course I continued to put it on until she is no longer biting her nails. My only complaint is it is super strong so when she was eating her chicken nuggets and accidentally put one of her fingers near her mouth she was complaining that it tastes gross and she couldn't enjoy her meal. Of course as a parent you need to know what you're feeding your child so I took a taste of the application to see what the big deal was and oh my gosh it definitely tastes horrible and storms your whole mouth. I now feel guilty for putting it on her fingers but at the same time this will keep the germs away and no more nail biting.

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.

I have been biting my nails since I had teeth. Nothing has ever worked esas I got older because I know I can just go wash it off. The only thing I have found that will take this off my hands is brake cleaner. This stuff works very well for stubborn people like myself. But it only works if you put it on!

Has a nasty taste, so if you are one to luck your fingers during baking cookies, don't put this on!!!

I always forget to leave reviews, but I must for this. I thought my 6 year old was never going to stop sucking her thumb. You would see it in her sonogram pics, and nothing seemed to deter it (not even peer pressure). This product has completely stopped it, and she doesn’t fight me putting it on her nail. I’m so thankful! Try this if you feel like your child will never stop sucking their thumb!

I know what you're thinking, you tried bad tasting nail products before and they didn't work. I'll tell you why I think this product is different and more effective.The biggest difference (for me) is that this is NOT a nail polish. The problem I noticed with some of the other bad-tasting nail products is that they are more like nail polishes, which always leave a residue. Ironically, this residue sometimes induces me to bite, especially when it starts to flake or crack and I want to get it off because it looks bad. This product, by contrast, just evaporates away after a while (yet the taste remains). There is no flaky or hard residue. Can't even tell it's there.Second, the ease of use and application method, especially for guys. I don't want to carry around nail polish, or apply stuff to my nails by dipping and applying as if I was painting my nails. This thing looks like a highlighter. You just click and it saturates the brush to apply. You can put it in your pocket, or leave it on your desk at work to apply as needed.So far, this (in combination with a fidget toy) has stopped my nail-biting after 25 years. Thank you for this very well engineered solution to this vexing problem.
