Trickier to use than simply dripping a solution into a vial, but should be more accurate. just faster and easier. The standard battery didn't make good contact, every time I opened the lid it would shut down making it impossible to use as you had to open/close it twice to do a test (calibrate then measure). I replaced it with a new battery and everything was fine.
