Every hydro store i've ever been to, and the few people I know in town all sing the praises of blue lab pens. but their prices are a bit steep to me. Some people say to just pick up a cheap $15 pen on ebay every year. But I have heard a couple of pros say that the only pen that matters is one with a changeable probe for when it wears out.

Anybody here use an Apera pen? Found what looks like a good one on amazon. interchangeable probe and comes with everything it needs. https://www.amazon.com/gp/product/B01ENFOIQE

Looked at it doesn't seem bad. Close to the same price as my blue labs one and I haven't had to calibrate it in well over a year. I check it just has always been perfect. I've used the Hanna and a few others as well as drops I mean I like mine but try it out and let us know.
