I am a little disappointed so far. Nowhere in the instruction booklet does it say to treat the area 3 times. So for the first 1.5 weeks I did only one pass over all of my treatment areas. It wasn't until I saw the little card with the offer for the Reviver after leaving a review did I see that there was a "NOTE: Make sure that you pass each area 3 times and use the device on level 6 or higher." I had been using it at level 7, thank goodness. I have been treating each area 3 times for the last 2.5 weeks. It takes a really long time. I am doing my legs, bikini area, and underarms and it takes at least 2 hours. I haven't noticed any decreased hair growth yet, after using it twice a week for 5 weeks. I realize I might be behind since I hadn't been passing each area 3 times for the first 3 sessions, but I still would think I should notice something at this point. I REALLY want this to work, so I am going to keep using it. I will update the review after 8 weeks.
