£18, CSV export, argument over in thirty seconds. i own four and i will lend one to anybody who asks. the number of disputes on this site that a logger would have ended is genuinely depressing.

NEVER. THE. DOOR.
two below-spec results on this site this quarter traced back to a mixed vial in a fridge door. the door is not a joke, it is the single most common storage error we see.
can confirm, it was mine, and it cost me a vial and a great deal of dignity.
your dignity bought several people a working fridge shelf. good trade.
