Worked fine but please note the factory is unable to fix or replace batteries or sensors for less than $150 so this will be a biannual purchase.

I purchased a unit with a calibration certification of 22 Dec 2020 and first activated it in May 2021. It had an expiry warning by August. Another unit purchased at the same time just displays random fail message even when just sitting on my work desk. Pretty ordinary unit in my opinion
