This product is garbage. I mixed the sizing powders as directed but the sizing process is not working as it should. The calibration process did not identify the correct solution and ended up calibrating the 9thpH solution as a 6.86ph solution and I briefly got it to identify 6.86 once but then when I tried to do 4, 01 it just kept blinking and never calibrated. Then I put it in solution 9.whatever and it showed 8.87 and I pressed calibrate but it chose 6.86 again and now when I put it in 4.01 it shows 0.00 lol, what is this ridiculous thing and does not work at all as described.
