Apera Instruments ph20 pocket tester

My Bluelab pen died and bought one of these. So far it seems to work well. Anyone else have any experience with it?

Not that one. But I got pc60 5-in1. worked great, until it didn't. Tds stopped working almost right away. Probly do to improper storage on my part. pH was always solid tho. Was gonna buy a replacement probe but then they raised the price. Probly shoulda stuck with separate meters instead of a combo unit.
