Eh, the sensor in the middle is the same material that SeaChem uses in their MultiTest kit, so I trust it. My family has been relying on SeaChem for years for aquarium products. Obviously, if you get a spike or dip in PH in a regular test, you will probably want to formally test for ammonia, too. It also causes zero panic due to false positives since it only tests for NH3 and not other types of ammonium. Maybe not the best for a large aquarium community, but does its job for my little tank.
My strip thermometer has been fairly accurate when cross-checked with a glass one. If I weren't a broke college student, I would definitely invest in top-of-the-line products for my little guy. But for now, I think it sure beats the plastic cup he came in.
