Digital PH testers

If you are using a digital PH tester could you please state which one and if you are happy with it. I plan on purchasing one. Thanks

I have a milwaukee PH controller with a digital PH probe. The first one I got blew up when I plugged it in. Milwaukee wouldn't pay shipping for it, so I was out $15 from the get go... not terribly pleased, but the replacement worked reasonably well. Just make sure you calibrate it once a month - they tend to drift.
