Debra Edgeston: After the train derailed in Ohio. And the Canadian fires. We were scared our water would be affected. This little device provides an excellent reading !

Addison McGregor: It’s tough to calibrate but it’s worth it for that amount of money

becky watkins: This is a piece of detritus. You know, the stuff the fish leave on the bottom of your tank. And I don't mean the food. It is actually worse than an off brand pH calibration solution I purchased. Amazon, you need to start carrying some quality products. I have been in the aquarium hobby since I was five. Started with a Trinidad guppy, a minnow and a 1 gallon Mason jar. I am 76 now and I have seen some trash over the years but these last two purchases were horrible. All I wanted was a pocket meter for a quick check. Followed the directions to calibrate. Carefully measured 250 ml of distilled water and mixed the powder until completely dissolved. Waited the five seconds and counted the 3 flashes and cleaned with distilled water, dried and moved to the next calibration solution. Went through all three. Just for kicks and giggles I put the meter in some water from my saltwater tank. The pH in it usually runs 8.1-803. Not with this thing. Nope, it was 4.6. I no longer trust the reviews because I don't know if I am even getting the same product. Evidently, there is a lack of quality control in the manufacture of the two items I purchased. This meter and an off brand calibration solution....

J.L.G.G.: Se necesita calibrar, para poder usarlos, y los productos que requieren para la calibracion, son muy difíciles de conseguir, y por lo tanto, no he podido usarlos, para lo que los compré

Ted D.: If you just need a simple inexpensive ph meter, then get this one. These meters are very delicate, so be careful not to drop it or bang it. It will last a long time, as long as it’s taken care of properly.
