Seriously if you have any kind of dexterity/strength issues and you don't have someone to help you open this, don't buy it. It took me 20 minutes to open fully. I really just bought it for the trimmer with the blade guards which works as I expected it would for longer hair. The other attachments aren't great and the funnel shaped eyebrow trimmer one seemed to be getting hot after barely using it. The separate shaver is fine but I don't really have a use for it, I tried it on my arm and peach fuzz on my face and it works but I wouldn't count on it for a great close shave or anything. If you need a trimmer this is a decent price and it's a nice compact size, if you want any other part of it I would buy something with better credentials
