Best pH pen I've used so far. I've tried hannas and oaktons, but like this one better. The pen takes a few seconds to deliver a reading, but it takes and holds a calibration well and feels really sturdy. If you are taking a ton of readings the lag may be annoying, but on the plus side you don't end up staring at the pen waiting for the reading to stabilize.
I've been wanting this pen for a while now and its working great so far. Calibrating it was a little confusing at first but I got it down and it's reading accurate I use the ph strips as backup sometimes so I know everything is good. I like that I just buy probs now as replacement instead of new pens. No more bluelabs lol.
