I bought this from China to test it out so that I can buy the more expensive one later. This tool actually works for what it's suppose to do, my face looks firmer after using it a week. It is cheaply made and I would recommend using it 2 to 3 times a day do at least 20 reps each time. I'm afraid to use it for long periods because it might break and your jaw starts hurting after a few reps. Sometimes your lip might rub on it and hurt if you do it too long. But as I said after using this one and seeing results I'm considering spending more money for the brand upgrade! Hey think of it this way you exercise your body to be healthy and to look young so it only makes sense to exercise your face muscles to lift them up.
