Great Quality, Great Price By Griseum on 1/9/14

The build quality seems to be on par with any other (more expensive) ORP probe. Have not had any problems like unusual spikes or drops, Comes very well packaged and protected (especially the electrode). Calibrated easily with the 400mV solution available from BRS.

Appears well made. Decent price. Running this on the Apex controller. Gave what appear to be normal readings within a day or so. Starting using Ozone with prior readings in the 230 range and now up above 300 within a week.

Excellent quality. Reading is very steady. Does not jump around at all like the other cheap probes I have used. Very accurate and craftsmanship is of high quality. I will come back for these when I need another replacement. High quality just like the expensive probes, but with a nice price tag!
