i havbe used cheap ebay ph/ppmmeters, for last 10 yrs., and they do need recalibrated more ofter than a guardian or expensive hanna, they are just as accurate. I bought the top of the line hanna pen, about 10 yrs. ago and it shit the bed within 6 months. The one I use now cost under $20 and I've used it now for like 2 yrs., and I just proved it to a friend , it reads exact and when it goes, I'll buy another under for $20 ph/ppm meter. Another thing i have found, is they last longer when stored dry.Yes PW a necessity not to skimp on.
I didn't quite understand the "continuous use" option between the Guardian and the Combo.
Plus I won't purchase these type items. From a third party supplier again.
I say roll with, dont let a perfectly good mood light go to waste! .
