I have the rectangular one from BBB
I have a cheep shower mirror that I use to wink at myself with. Seriously I don't use the mirror, I've pretty much got the head memorized. If you do use a mirror, then I'd recommend using a cheep defogger spray for motorcycle helmets. I've had a small bottle of this stuff for years in my bike bag, and it works great in the shower. As a temporary fix, clean your DRY mirror with Barbasol shaving cream. It will keep the mirror fog free for a couple of showers.mindfungus
