First review. I was a little skeptical at first but I must say after a week with them, they are great. Sugar free, no aspartame. I stopped chewing gum recently for the ladder but came across these recently as I why looking for solutions to define my jaw line and I dont really care much for facial exercises. I can put them in and chew on them from 10-45 mins twice a day. Be careful with the initial few bites as it is really hard. After you soften them, You get into the groove after and get use to feel of it. Just go slow with it and work each side evenly. The taste subsides in more or less 5 minutes but that’s not really the purpose here. It’s to train the jaw. It is the perfect harness for most, anything harder would just hurt the teeth. I got the mint ones and thinking of ordering more already.
