I ONLY GAVE THIS 4 STARS BECAUSE I AM STILL NEW AT IT. I,M SURE I WILL GET GOOD RESULTS IF USED ONCE A WEEK, AS INSTRUCTED. IT SAYS IT CAN BRUISE THE SKIN- A FACT I NEGLECTED TO READ BEFORE I USED IT. SO DON'T LEAVE IT IN ONE SPOT A LONG TIME- I CAN SEE SOME RED SPOTS WHERE I CONCENTRATED IT. SO WE WILL SEE. IF I BRUISE- IT WILL BE MY OWN DAMN FAULT. JUST KEEP IT MOVING GENTLY ON YOUR FACE. SO FAR- SO GOOD! IGNORE MY OTHER RATINGS- I CLICKED ON THEM BY ACCIDENT. I THINK IT IS GOOD!
