Are strops from Fromm any good?

I get these ThankYou rewards from a credit card I use. Turns out I had quite a bit of the built up. I wanted to use them before they decide to take them away.

To my surprise, they actually have some straight razor products available. Col. Conk soaps, razor handles, mugs, Fromm 5/8" razors, and Fromm strops.

I'm building a small set of gear to keep at my parents house, so I don't have to tote stuff back and forth. I got one of these Fromm strops, linen and cowhide.

Are they any good?
