Review (2/5): Meh.  But at least it has interchangeable parts.
It's a okay strop. I had to treat it with leather conditioning oil before the leather was remotely supple enough to get a draw even across my razor, and the synthetic back needed to be ironed on low. Might be better for knives.
What's interesting is that the hardware is the same as that used on better brands such as Straight Razor Designs strops, so if you order this and wish to upgrade, you can just buy a much cheaper replacement piece from them and swap it into this strops hardware with nothing more than a flat head screwdriver.
