Un producto que vale la pena 100%. Para las personas que dicen que no les funciona para su hijo menor de 3 años, es por el simple hecho de que a esa edad los niños aún están descubriendo sabores. A diferencia de un niño más grande o un adulto ya sabe distinguir. Mi hijo de 12 años, en 2 días dejo de llevarse los dedos a la boca, y a la semana ya las uñas comenzaron a crecer ya que tenía los dedos muy lastimados.

Llego en excelente estado, lo único que la niña este producto no le hizo nada ella siguió con el dedo igual.

I’m a nervous picker and this keeps me from subconsciously destructing my nails! I am obsessed.
This product is incredible. It keeps me from putting my hands in my mouth or anxiously picking! It’s the best reminder to help me grow my nails.

Bitter stop
My kids are both thumb suckers, and their dentist has strongly been encouraging me to intervene with my 4 year old. He had stopped within a week and is still thumb-free (and proud) thanks to this (somewhat costly) bitter marker. Tried a little too early on my 2 year old (not advised)--definitely an emetic for her 😳

very disappointedI’m
At this time quality is very poor! Smell so bad, like alcohol and no result like every time . I feel it’s not oil anymore. I was very disappointed.

Made my kid nauseated
Tried this product to get my son to stop chewing his hands. On the first day of use, I got a call from the school health room that he was complaining he was nauseated and didn't feel well. I encouraged them to wash this stuff off his hands really well. He was completely fine and not ill at all, 30 minutes after drop off I'm getting called. Put it on right before leaving the house. Will not be using again, straight in the trash. This isn't eligible for refund, would not recommend.

Doesn't work
It takes 2 minutes for my 3yo to start suckling her fingers again.
