I'm not too happy right now. My nuppin' came today, along with new imr 2200 20amp batts and
omnitester (from rtdvapor) The omnitester is useless! It won't read the resistance of any of my attys! Not the RM2s, not the kayfuns... I put an old evod on it and it did read that

I was going to start building the nuppin but now I don't have anything to check resistance unless my build is .8Ω or above. (using a provari as a resistance checker) The well seems way too deep to make a connection to make a reading. The description stated that this thing will read any 510 atty but it doesn't at all.
I emailed rtdvapor through their website and asked for advise on what to do because I essentially spent $20 on a piece of junk!
