Shame on us for saving money.   ;D

Things to look out for and consider with a cheapo pH meter are the resolution and accuracy.  Make sure that the model is accurate to the hundredths place, not the tenths.  I also have a third buffer solution to check the accuracy of the meter beyond the two used for calibration.

Lastly, think of these as throw-away items.  They rarely last beyond six months, let alone a year, though much better life can be had if you treat the probe end carefully.  It is really not much different than replacing the probe on a higher end model such as the Hanna most people prefer.

I store mine in low pH solution, which should theoretically prolong the life.  I don't have the experience to know if it makes a difference, but figure it doesn't hurt either.

I also keep mine in storage solution, and at 10 months old it is still working fine.  It is true that the thing doesn't hold calibration very well, but recalibrating it for each brew session takes all of 1 minutes.  Just a data point for you.
Risk of failure should be no deterrent to trying.

Even a fancy meter should be calibrated for each and every use.  Therefore the net time savings between fancy vs. cheapo = exactly zero.

I’ve had 2 meters and this was the easiest to calibrate and use

I Use the MW101 and it’s dead on accurate.  Although now I’m not as interested in using it, as brunwaters estimate is always correct for me I just roll with that.   After spending $70 for the mw101 I kinda wish i went with the cheaper pen styles.  The cord is super annoying to work with.

Thanks again guys for the helpful insight. I’m leaning toward the Apera ph60 but also getting a cheapo and doing a side by side comparison.
