Review on ⚡️ Milwaukee MA911B Electrode Electrolyte: A High-Performance Solution for Accurate Electrode Calibration by Brad Lovro

I have used 2 of these probes in a reef aquarium with an apex controller. They've been running for 2 years and to my surprise they're still going strong. I bought a few more thinking my 2 year olds were bad, but I recalibrated them and they were within 0.02! It's damn good in my book. I swear they last longer than dual-link BRS sensors that leak or fall out of calibration. Will stick with it and save a few bucks. Every little thing helps in my hobby.
