For what it's worth my UltraSmart is like 6 years old and still going. Gives me results consistent with my other meters. Had to replace batteries recently, but no issues with it's reliability.
That is good to know Kari. I guess I should bring out my good old Ultra One Touch. ( just in case ) I have a bad habit of leaving electronics in my car during the winter. Like my phone and my meter. I should see if changing the battery would give it a lift.
