Review (4/5): Once you go Epil...
I never thought I'd say this, but once you start (and get used to) using a decent epilator, it's almost impossible to go back to shaving and Braun makes some nice ones. I've used a few different models and this isn't a lot different than the last couple, but it was my first wet/dry version and I like it.
I don't recommend using the epilator in the shower (standing up) unless you've got fantastic balance and a super non-slip tub or shower, because even as used to it as I was, I still jumped a few times. I found sitting down to be the easiest way to use it, either immediately after a bath or on the edge of the tub during a shower. It didn't work as well on dry-ish or moist skin following a shower/bath but did great on actual wet skin - after using it for a while, I actually prefer it to using the epilator on dry skin now (I have painfully dry skin though and your mileage may vary).
I think the pain factor is what keeps most people away from epilators. I won't say it's painless, but the pain varies depending on where you're using it, what heads you're using, what speed you're using and of course, how sensitive you are. This is basically large-scale, fast tweezing and the first time, it stings. Cooling off with the included soothing pack, if you need it, helps, as does some cool lotion. It gets better - I barely notice it now and honestly, being able to go two-plus weeks without having to shave/epilate is worth five minutes of any sort of stinging.
