Bro,
I remeber when they first came out and they where all you could get lol... Then they where ok, a tad dirty meaning you could see stuff floating in it (Not my fav thing to see hehe) and sometimes 1/2 cc or so underfilled but that was a good while back... Not sure the quality of them now they are normally so cheap that no one dares to counterfiet but who knows lol... I would use only if I was broke or just couldnt get anything else, there is just to much to get out there right at this moment, way to much....
