Ordered it off of EBay from ohio-pet-supply. Got it way later than I should have, and he didn't even package the box! So I got it with only 2 test vials and the box was mangled beyond belief. Needless to say, the guy got some negative feedback. Apparently other people have better luck with him based upon his overall feedback. Oh well...win some, lose some. Anyways, the kit is great! So much better than my dinky little test strips! Thanks for the reccommendations guys
