I’ve just received my JAWLINER and so far I’m really impressed with the product quality. The gums feel very durable and well-made, and the taste is surprisingly good for something this firm. I’m already using the hard version and I can definitely feel my masseter muscles working much more than with any other jaw trainer I’ve tried before. I haven’t noticed visible results yet since it’s still early, but the workout feeling is strong and promising. I haven’t tried the ultra hard gums yet, but if they’re anything like the hard ones, I’m sure they’ll be just as effective.
