Bought some of them a while ago. Better than the very cheap WallyWorld towels. A mid quality towel. They have remained fairly plush after several washes.
I just used the window towel (very neat tight weave, not plush) and it did an AWESOME job, no streaks or lint. I always get lint when using my Pakshaks on glass.
I like them enough that they form the bulk of my towel supply, and haven't really sought mail order alternatives because of this. Even if they're a bit better, I have no complaints about these towels and prefer to source my supplies locally if possible.
I found them at Zellers (Canada!) last year; they have them in blue, yellow and white, making it very easy to keep them seperated for different detailing duties.
They are the only MF I've tried, just because they're so darn cheap.
