bought a bluelab EC pen, accurate as a the death star AND no calibration- with a 5 years replaced with new/current model warranty.
how much for this wonderful apparatus?
$130!
make it rain, bitches
I hear you but that doesn't help us color blind MF's outabsolutely, gsf. why i use the ph drops.
Hannah meters are complete and utter shit, I bought 5, 2 wouldn't calibrate. Replaced them, one bad out of the box. 3 more failed a month later. Replaced them all under warranty again, now I have 4 left and 2 of them won't calibrate 9 months later. At this point I think all 5 have been replaced twice in less than a year. That's a 200% failure rate! lol
