anyone want to discuss ph testers?

what do you use?
how accurate is it for you?
how much did you spend on it?

ive had a hanna "checker" for a few months now, and it seems to be retarded on occasion, other times it seems to work just fine. i dont get it, i calibrate it every time i use it, sometimes i have to calibrate it multiple times in one session....i store it with the cap on, in 7.0 solution. sometimes it will read the same exact water completely different 5 minutes apart from testings, i dont get it. other times it seems to work great.

anyways, just wondering what everyone else uses/ recommends, because if this keeps up, im buying something else...im thinking i shouldve spent more in the first place.

i also have a hanna....ebay???
it sucks..but it always stay accurate enuff to keep my plants alive and from going into nutelock so i say, if its not broken, dont fix it..

i have a cheapo from ebay, its yellow, i thinks its a hanna. one time it was way out of wack, but i re-calibrated it and it has been great since then. i check the calibration every week or two and its always right on. ive had it for well over a year now.

I have a cheapo company called Hold All makes it, cost me all of $15, and always reads water the same ( unless I've added something ). This model also has moisture gauge and light meter.
