Derby Razor for Body Shave

I have always been curious about this disposable:

Derby dmakes a variety of DE razor blades ranging from the relative mild (dull???) Derby Extra blades to the relatively sharp USTA blade. I have no idea where the Derby body shave blades might fall on that spectrum. Personally, I hate lightweight disposable razors, but for the low price, it might be worth experimenting. If you do not like them, you are only out $4.
One interesting thing about the razor is that it appears to be an open comb design. That is unusual for disposable razors.

kind of looks like a gillette guard, from what I can tell with the cover over the blade and comb area.

Don't know anything about these but I can tell you that Dorco's double edge disposable (their version of a Trac II) is the worst razor I have ever used. Well, maybe not THE worst but right up there with the worst.
