Legit Gen 7s?

When I started my tactical route, I purchased half a dozen CATs f9r less than $20 each. Some from amazon and some from Tacticon Armament. For the last year or so subs have noted medical, perhaps life saving equipment, shouldn't be "just as good" and I agree.

Just purchase two CATs from a medical shop, but they feel and look eerily similar to the ones I have, except grey time stickers and a stamp. Anyone tell by looking if I just wasted $65 on knockoffs?
