Critical failures By John on 1/14/2015
John wouldn't recommend this product to a friend
When the unit works it's great, but two separate times the unit has failed to turn on/off the CO2 regulator for my calcium reactor at the appropriate pH. The first time it happened I unplugged the unit for a few days and it started working again. After the second time it never went back to working properly.

This ph controller is very well built. However, the ph probe is very sensitive. I tried to have my controller stand upright on a shelf, it tipped over and now the probe seems to short out or lose connection if it's moved, the display freaks out for a second.
I wish the unit had a way for mounting it on a wall.
