I haven't seen steris stuff in a good 5 years. Could be more....Don't know for sure it that is good or bad. I'm leaning to "bad" since I know the last I heard anything about them, there had been this big contraversy over the company in the US getting into legal troubles, and shortly after hundreds of Steris stuff being counterfeited to fill street demand. Go with a UG lab bro, ....piece of mind you will have some real solid good ones out there too.
