Having looked at quite a few of the epilators on Amazon, I opted for this mainly due to price. It is a good all-rounder, with two epilator heads (one for legs and one for bikini line / underarms) plus a shaver and trimmer. As for the pain, it's nothing compared to my old epilator, using it on my legs I experienced a slight tingling whilst using it on my bikini line was a little more painful, unsurprisingly!
Overall I'm really happy with my purchase and am doubtful whether the extra money would have been well spent elsewhere.
