I bought 2 bottles from them. It took 3 weeks to arrive. The old stuff had a bad clumping problem. This was pretty decent with only a few small clumps which broke apart easily. I love the stuff and my mk85 sures seems to agree with it. easily cleaned and I can go about 5 shots before swabbing a clean patch in it.My brother who shoots a master hunter can take or leave it. My gun would only have a small amount of white powder buildup in the last inch of the barrel.
