I have ADHD and ME and really struggle with shaving my legs in particular (also bikini line). I know that the Philips Lumea gets great reviews on Mumsnet and a lot of people find they don't have to shave again for a long time, sometimes forever. But having just logged on to their website, I'm overwhelmed by the choice. Which one do I need? I want to do legs and bikini mainly, underarm would be a nice extra but is not essential. I want the results to last and for it not to be a nightmare to use. Which one is best?
