Nirvaanaa Jawline Exerciser Tool For Unisex For Jawline Workout Double Chin, Face Workout For Face Fat Reducer Jawline Exercise

Not worth the money

Nice

Very good for jaw exercise and very awesome alternative to chewing gum, it's harder and works that particular jaw muscle, Only bad thing is that it BROKE after 5-6 days of regular use. Wouldn't purchase again tbh, but if you can afford 5-10 pieces it would be good.

Nice product and good quality.

The product broke after four uses. Either I have shark teeth or this is a low-quality product.

I feel the rubber is extremely hard to bite. Its next to impossible to bite. I used it for 2 days and i had severe painful front teeth and jaw joints. Absolute waste of money. Strongly recommend not to buy this one. Find a better one.

The media could not be loaded. 3 days use product damage

It’s a brittle material, don’t buy…after few uses cracks are coming.
