I definitely did NOT get a week's worth of hair removal from the mitts. More like one day, I'm afraid!!!
However, I did like them. They leave your skin nice and smooth, and the hair seems to grow back more mercifully - softer - than with shaving.
But as for longevity - not so great, in my experience!
But I still liked them.
Be careful not to rub too hard or your skin will get kinda burned from the friction. The trick with them is that even though they don't feel like they're doing anything when you rub softly in circular motions - keep doing it, check in a minute, and you'll find the hair is gone. So don't press down harder, even though you're tempted!
