Andis Slimline Pro Cord/Cordless Beard Trimmer

I spent the extra money for this product vs competitors because of Andis' reputation for quality. I've always bought cheaper beard trimmers and decided to spend the extra money to get something that would last and maybe work a little better. The first two times I used it, it was exactly what I had hoped and then some. Super sharp blades, cut really well and the battery life was definitely way better than the norm. I use this primarily to trim my beard and keep things nice and short around my ears, and for a brief moment, it did a better job at both than any that I've owned. Fast forward to yesterday and it has gone COMPLETELY dull! Both times I used it previously, I cleaned it thoroughly, applied some of the oil that it came with, and kept it fullly charged in between uses. When using it this last time, I noticed right off the bat that it was pulling my beard hair pretty badly in one spot on the blades. It was still cutting ok-ish aside from the pulling (so I thought), so I brushed it out well and proceeded to do a quick pass around my ears (where my hair is already extremely short but bothers me when it gets any longer than stubble). This thing completely TRASHED my hair to the point that I first thought I had gotten something sticky in my hair somehow. My hair is now split all the way down to my scalp on both sides around my ears and sideburns. To the point that it almost feels like I burnt my scalp. My GF looked closely and said it looks like someone took a razor blade to each blade of hair and there are a number of hairs that didn't even get cut. I have no idea how a supposedly "high end" trimmer went dull enough in 3 uses to shred my hair, but this is obviously not acceptable. I will be reaching out to the seller and/or returning this item today. Very disappointed.
