Because of this I started using an electric beard trimmer with really low trim length (0.4mm). It does not result in a clean shave but close enough (and I don't look like a teenager). But the best part: You pay once 60-100 bucks and can keep using it for a few years (in my case 7 years as I just had to replace my old one).
It's perfect for my skin, and a super fast shave. Just enough stubble to look good.
Lapped the blades once, just put a new one in. Hard to beat the ROI on that!
