Product review (5 stars): Ordered 4 to help regulate our AC system better with air load and damporing
We purchased the temperature only model (no humidity).  Ordered 4 to help regulate our AC system better with air load and damporing, etc.  1 came in C instead of F, not sure how to change it, but NBD we can work with that.  Very accurate and the perfect shape and size for a small digital readout.
UPDATE - The company refunded us the costs of the 1 unit that accidentally came in C instead of F - 5 Stars!
