It's a groomer, not a haircutter [SEP] The item has the attachments to cut hair but it is not designed for full-on haircuts.  It's to keep you groomed between haircuts so you don't have to go as often, hence it being called a groomer. Also, if you're having trouble charging it, that's because you're not likely following what it says right in the instructions...it must be charged for a FULL 24 hours before the first use.  Do this, and it works fine. The neckline trimmer is a godsend.  My neck hair grows faster than that on my head so this does nicely for a neckshave when I don't really need a haircut yet.  Professional haircuts are getting too expensive everywhere to go in every 3-4 weeks when you don't need a full cut but do need a touch-up.  This does the trick in that respect.  The nose hair attachment works fine...again, the idea is not to get to the point where the hair is so long and thick that it doesn't work.  Groom it, keep up with it as it grows.  That's what this thing is for.  I have misplaced one of the attachments, unfortunately, so will be buying a new one but this does a a great job, better than the bigger, bulkier products out there.
