Obviously QF is far and away the most popular brand out there and on this board. I have seen Dr. Johns used about 5 times in the past 1 & 1/2 on this board and have heard no complaints or failures. I forgot, is it pre mixed or powder you must mix and then is only good for x amount of time?
Yeah...I get what you are saying. Might as well spend the money and get the whole thing..

Dr. Johns is concentrated liquid...mix w/ 2-3 ounces of water and away you go...which from your previous posts, seems a better route than the powdered variety.

I'm a little more inclined to use the urinator as I am going to have do drive 40+ min. to the testing site and then sit for who knows how long so I'd rather swap a fresh set of batteries when I get near the testing site then have to worry about a fresh heat pad overheating the sample...

But I will test w/ the QF as well and see if I can get some consistent results as I'd rather have a small bottle crotched than the larger urinator setup strapped to my leg w/ an ace bandage. Thanks for the reply.
