You wont have to get a new tester for years. Also this tester is waterproof so if you drop it into the water its not a problem. If theres anything you dont want to cheap out on its your PH tester. Bad PH is a sure fire way of locking up your plants so invest a little and get a good one.

Thanks a lot for the suggestion but the tester you listed is only $30 on ebay:wtf:. Just thought I'd run that by you. Friend of mine was using that same meter but he ended up buying some $200 meter because he said the Hanna was junk. I may have to find out for myself cause he's just picky about shit sometimes
