Excellent product well worth the price. I have had these chews for a week now and wanted to share my thoughts and advices. Just to get this out of the way first, these WILL NOT give you a sculpted jaw if you are not also losing body fat through diet and exercise (weighttraining/cardio). Everyone has abs, but you cannot see your "six pack" unless you are LEAN. Same applies to your jawline. With that being said, I am very impressed with the overall presentation, value, and quality of these chews. You are actually paying for four chews, not one - with each color offering increasing levels of resistance. This increase in chew resistance is exactly as increasing resistance in a gym weight lifting training regimen. So as your jaw gets stronger, and those muscles start to build, you are able to keep increasing the tension for even greater continuous jaw gains. I have used these extensively for the past week and have not noticed any damage or degradation of the chews. Now the bad side (but there is a fix), if you are prone to an easy gag reflex, then you may have to modify the approach you use with the chews. I gag easily and when I try to insert both chews on either side, I am often unable to keep them in for too long before I wretch and have spit them out. Easy fix though. I am now doing each side separately with about 30 repetitions per side. I am still getting a good workout and achieving that soreness - which is indicative of muscle tearing, rebuilding = GROWTH. Overall, the Mayena jaw exercisers seem to be a solid investment.

Es un artículo de buena calidad y hasta ahorita cumple con lo antes mencionado

I liked them a lot. They went on for quite a bit before giving up but overall I am happy with my purchase. Nothing lasts indefinitely. So recommend getting them.

Arrived on perfect time, within use of a week, has made an impeccable difference.

using these are good exercise but they are a bit soft and teeth can cut into them creating holes if one has sharp teeth.
