Bear in mind the leccy razors essentially shred/rend the hairs off. Not in a painful way like an epilator, but it's like cutting a hedge with a hedge trimmer instead of secateurs/loppers. I think that's a fair analogy when you look under the microscope at hair cut with a blade vs shaver. It does the job in a pinch but you'll be glad when you can return to wet shaving just for the quality of finish and satisfaction. I made the mistake of buying a cheap Braun travel shaver that runs on AA batteries years ago. Total rubbish. I used it twice, then went back to my Mach 3. That said, my step dad used one of those Philishave things with the circular grater things for most of his life and seemed presentable and content enough. I think if you have no choice, keep your expectations in check and don't blow too much dosh on it, but don't go too cheap. Or grow a beard for the duration and have the satisfaction of shaving it off ceremonially when you're able, assuming this situation is temporary (which I hope it is). Most importantly, get well soon.
