Product review (4 stars): Display is unreliable
**UPDATE** The vendor contacted me!  They were extremely responsive and sympathetic - they immediately sent out a new unit which works perfectly.  Must just now wait to see if the new unit outlasts the old one.  Three extra stars for *outstanding* support service!!

---- original review follows ----

I bought this product at the end of June 2017 and by November 2017 the clock display had begun to fail.  The attached photo indicates how the multi-segment display has started failing.

In other respects, this device seemed to work well, including the outdoor sensor.
