I will say that is the cheapest meter I've seen. Why not just get testing kits? If you test DO once a week you can get ~100 tests for ~100$ and that's nearly two years of testing. You really need testing kits anyways to validate and correct your meters, as they do tend to need recalibration every few months or so.
