I had exactly the same issues when I started, I could shave my sideburns & cheeks fine, but the razor either skipped over or stuck when doing my chin & below my nose. It was completely beginners technique on my part & time/experience is sorting that out for me. I'm not saying it's not the blade at fault, but after just 2 shaves I wouldn't discard the idea that your technique needs improvement. It took me 2 months before I started to get even vaguely okay with it, & after 4 months straight shaving I can do a good impression of somebody who knows what they're doing, but I've actually got a long way to go before I'd class myself as any good.
