Daum-exol Film-forming solution - 10 ml. Against sucking toes and nail biting

No effect for my daughter

Amazing product. I have been using this product for five days and my son has not sucked his thumb once! I highly recommend it as no amount of bribing or anything else would help break the habit.

useful for the first few days, i was so happy, then it made no difference:( i think it's not bitter enough.

Little girl had it on and it made no difference

As a long time nail-biter (> 40 years) ... this was the product that help me stop!This is a german product, which I came across while living there. I prefer it because it dries really quickly, your fingers don't look like they've got nail polish on which is good for blokes ... because polished nails may just get you ridiculed (personal experience). I don't find it as tacky (sticky) as it's UK counterpart, and it does seem to layer and strengthen the nails.To the reviewer who gave it 1-star because their child continued biting their nails even with this on .. I can also say, as a child, I got used to the bitter taste of the other well know product, because I was just that stubborn, and if your child has that mentality you'll probably just have to wait ujtil they're ready to stop themselves. Then, I'd definitely recommend this.
