Clock was not cheap and the first delivered one only worked a couple of hours. However, Wayfair was great about the exchange process. 
2nd delivered clock seems to be working fine - for about a week so far. Believe it has a two-year warranty from purchase if I recall correctly. 
It's great looking on the wall (but it appears to be made of plastic - which you cannot tell from far away or unless you handle). The second hand is a nice feature.
When selecting the color, remember to consider the wall color behind it as it shows through.
