"Works like a charm."
"Works great and saves me a lot of time and trouble."
"This isn't a 'smart meter' it's just a pH probe and a dosing pump with set variables in the controller. If you treat a gallon, then one pump from this doser and your pH will sky rocket in the set direction."
"You will not regret this purchase."
"Meter will not stay at a consistent or even close ph reading, This causes the dosing pump to give more ph solution then it needs."
"The doser pump seems to be decent, and the sensor is accurate but the actual communication between sensor and doser is terrible, it should only turn on for 5 seconds, turn off, check pH, turn on for another 5, check pH, until it reaches the desired level."

"I've been using this oil since the early 1970's and have had no problems with my vacuum pump."
"Very good oil, I used it after using the included oil with my vacuum pump and saw an improvement that although small it was an improvement nonetheless."
"Good product and really it's actually much cheaper to buy it in this size than it was to buy single quart because of what they charge for shipping on quarts."
"I use in a freeze dryer which requires top quality."
"It was a perfect product before and it's just as perfect now!"
"I recently had some issues with the dehydrator, and as part of the process I changed the oil, just to ensure that oil was not the problem. The problem is that I used a different oil."
"I run my pump sometimes for 24 + hours for my vacuum stabilization process and it seems to hold up great!"
