I have had this product for over 2 years (in purple) and it still works like it was out of the box. I had never epilated before buying this, so I was a beginner. Epilation is painful the first couple times, but no worse than waxing (at least with this epilator) and the results are amazing. Plus, unlike waxing, there's no mess, no buying strips over and over, this thing pays for itself within a month with the lack of replacement cartridges and strips. I find this product works best for me on my underarms. For some reason I get ingrown hairs on my legs when using this or waxing, so I know it's not the product's fault. But on my underarms this removes hair like a dream, no 5 o clock shadow! I can go several weeks without using this again, and when the hair grows back it is much finer and more sparse. Some does not grow back at all.
All in all, for beginners and novices alike, this is an amazing product that pays for itself incredibly fast. BUY IT.
