at first I was thinking that there are cheaper kits out there,but like presser said "you get what you pay for." i bought one.
I like the two filters for extra sterility,the alcohol swabs for the extra sanitary use, it was simple and clean. I even requested that I needed a 4g kit at 150 per/ml and it came with the proper measurements to do so. It required a special e-mail but,I didnt have to play mathmatecian, now that's customer service, what other company does that?
