Spot on accurate according to my calibration solution. Solid and well constructed. Very nice pH meter for a very reasonable price. Update: Five months later and this pen is still spot on. If you don't have a lot of money for a ph meter this is the one.
First one worked for a week. Then everything was ph 4 - 5 even 7ph calibration solution. Replacement arrived promptly but was used and had scum on the electrode. Not cool. Buy 2 Etekcity's for the same price as this one and have a spare.
Does what it is supposed to. No complaints. Just use it occasionally.
