Review: The best way to keep from nail/finger biting! - My parents made me wear a similar product when I was a nail biting kid and I hated it -- but it worked. Stress & the pandemic somehow evolved to me biting my nails again as an adult, and I've been so mad at myself for restarting this habit. So I decided to look for the product that helped me stop once, and I found this one. And again, it works! I apply it every day/every other day; it dries quickly and it stays on my nails for at least 24 hours usually. It tastes absolutely awful, so just one absentminded finger near my mouth and I'm reminded to never do it again. It really helps break the habit!
Review: It just plain works - Six weeks ago, my wife persuaded me to try Fidyn No Bite, after all my nails were down to, or almost to, the quick. I was amazed a how well it worked, because, frankly, it’s not all that terrible, and besides, I was pretty lax about using it. After the first application, my hands went to my mouth a half dozen times or so, and the taste would startle me into putting my hand down. It wears out after several hours, so you have to reapply, which I did faithfully for maybe a day and a half. After that I only used it when I remembered, which was, like, every other day, then every third day, then once a week, and now never. But I found that when I put my hand to my mouth, I would remember the taste, even though the taste wasn’t actually there. A complete success, and I have a lot left, in case I ever start biting again. Great product.

## Features

- 【Moderate Bitterness That Works Just Right】Not too bitter to make you sick yet bitter enough to discourage you from biting your nails (or putting fingers in the mouth) ever again. The amount of the bitter substance in the product is carefully measured to suit the taste buds of most people. Effective for more than 85% of users, for those who do not see effect, hassle free for help is guaranteed.
- 【The Bitter Taste Can Stay On For As Long As You Want】One application will let the bitter taste stay for several hours and several applications for a whole day. The taste will not rinse off after normal hand washes. However, if you really want to get rid of the bad taste immediately (such as before eating your meal), a thorough soap wash will rid your hands of the product. With Fidyn no bite nail polish, you can get that bad taste whenever you need it but never let it ruin your whole day.
- 【Safe For Children, Toddlers and Adults】Bitrex solution is the chemical that most brands use as a deterrent to nail biting/finger sucking habit. However, we choose to get the bitterness from mostly organic plants such as bitter melon and licorice and we use the least amount of Bitrex possible. These plant based bitter substances are natural - non toxic and make the Fidyn nail biting polish safe and effective for everyone.
- 【One Bottle Is All You Need】It takes persistence to quit a bad habit and the average time to do so is usually around 2-3 months for most people. That is why our Fidyn nail biting polish contains 10 ml/0.34 fl.oz. of product which is enough for more than 3 months usage. One little bottle is all you need.
- 【Do our best for you】We will do our best for you. We recognize that not every customer will have the same reaction to the bitter taste, but we believe our product + our services will be great for you. If you are not happy with our product and services, or if your habit is still not gone after using our bitter nail polish, contact our CS team for a hassle free help.

**Q: Some reviews said doesn't work and some said works. Could someone tell me your experience？**
A: Regarding the bitter taste of the nail polish, we deliberately lowered the degree of bitterness for safety's sake, yet actually it is still very bitter for most people. And we know that one kind of bitterness would not suit ALL people, since people do have different perception of bitterness. Our product development team had tested thousands of people, and concluded that for the same degree of bitterness, some will say it's too bitter while others will say, it is not bitter at all. That's why we promise Money-Back to customers who are not satisfied with the bitterness of our product. At the same time, if the polish is too bitter, it may cause adverse reactions such as nausea and vomiting, especially among children, as you know, safety is also very crucial, so please undertand why we decided to lower the bitterness.

**Q: Could anyone share the Bitter feeling? Can I use it for mischief？**
A: For now, the Bitter is level 1,  however, many customers feedback not enough, so we have improve it to level 2 and will coming soon.  For mischief, actually, for Adults,  it's OK, they will mischief back to you. But for Kids, you'd better not do it.

**Q: Is this matte or glossy?**
A: It’s just liquid.
