Query: Not for fine hair

I had high hopes for this hair removal device. However, the first time I tried it, I ended up with burns all over my legs. Amazingly, I wanted it to work so much that I tried it again being more careful. After an hour, I ended up with some hair removal on one lower leg. The third time I also spent a long time and didn't get anywhere. I got results on the thicker hair areas, but the fine hair never went away, regardless of length. I could never get anywhere smooth. And forget about the knees or ankle area - ouch!Essentially, it takes way too long for little results. Shaving only takes a couple of minutes.
