can someone tell me why i shouldn't buy a few of these

Those are actually pretty decent drivers. I tested a batch yesterday and they all tested just over 700mA and run at 87-88% efficient.
 
look at some of that guys feedbacks.. something like 66 negatives on there, from poor build quality, to not shipping, to saying description said 9 watt and getting 3 watts, to to to.. i think i'd steer clear of that seller at least..

I know it's a crappy Chinese c.o.b but for less than $10 I'm thinking about buying four of them just to fuck around with.
Supra, just off of the top of your head do you know what cree or Bridgelux cobs these drivers would be good for?
 
out of nearly 10,000 transactions 66 negative reviews isn't too bad.
