I agree, I love the look of the Koopor plus (mine is the red version) and the weight and feel. The overall build is tremendous! The magnets on this thing would pick-up a car! Lol! But,...sadly mine still has a major problem. It reads resistance inaccurately. Wildly off! Not even close! I can take a dripper with a .25 build and put it on the Koopor and it will read .67! Then take it off and put it right back on and it will read 1.03 then the next time .37! It's not just the one dripper it's all of my drippers and tanks! It doesn't matter what type of build or wire also. I have tried a variety. I have measured this against my Sig 150TC and two different ohm meters. Same results. I don't know what I'm going to do about it yet but I sure am unhappy. Have you had a chance to play around with yours yet? I am just wondering if I got a bad unit or if this is a problem that has plagued the Koopor in general. I would be interested to hear your thoughts and experiences with yours.
