I installed it last year before winter. However, I didn't leave a review because last winter we didn't have many cold days. It reached a maximum of -6 degrees if I remember correctly. We didn't have any issues.
But this year, it reached -18 degrees on the first day. -15 degrees on the second day. And consistently below freezing for the next week, and it still didn't have any issues!
I didn't shut off the water like I used to with previous faucets to prevent them from freezing.
So I consider it truly frost-resistant since it can withstand such temperatures.
Also, it is a normal faucet that opens and closes like all other faucets.
Don't make the mistake of saying it survived in the snow. When it snows, the temperature hovers around 0 degrees. Especially if it rises above freezing during the day (as is usual), it can withstand a simple faucet!
Faucets don't break with snow. They break with sub-zero temperatures when the water freezes!

It's pretty nice, we'll see how long it will last.. Greek company.. supporting Greece whenever we can.
