I used recently. great price and the stuff was decent but..
a couple of the ampules were underfilled, but the thing that bothered me the most was the ampules were cheap, shattered a few of them.
otherwise, decent stuff.
For the price I've haven't seen or used anything better. Amps were tough to open even with scoring so just wrap the tip in a cloth and like lightening snap that bitch. Very good product however.
