Freezing Temp Alert, Freeze Warn Light: Flashes Below 42°F Available in Red OR Blue (Red) Batteries Included

Wonderful product for my situation. At a glance at the window, I could see the light flashing that meant the boiler had failed again. Love it!

Ive been thinking about buying some type of window temperature monitor for sometime and finally decided on this one. Arrived in the mail yesterday. Im impressed by the quality of construction and he simplicity of use. Think itll be perfect for my use. Ill be leaving my home here in Maine shortly for an extended trip so with winter temps still very much an issue in this part of the country, itll be nice to know theres a visible warning from the road should I loose heat here in my home. Already talked to a neighbor wholl be keeping out an eye plus the local police patrol. If youre going to be leaving your home unattended in a cold part of the country, think this is something you may want to seriously consider. The order went smoothly and I received by the promised date. The only delay was one day due to a snowstorm earlier this week. Hey, thats why Im buying this in the first place.

Have not had a problem yet ,so have no idea

works as expected

This is the second winter I have used this light. Got a call last week saying the light is flashing! Good to know as when we had someone check it out the furnace wasnt working. Got a repair guy out and was able to get it running before anything was damaged for froze!

On time reasonable price

used in pump house

Holy crap works great saved my friends house. They were going south for the winter I got it for them as a gif. I was coming home one day and it was flashing. went in and it was cold they ran out of propane called him and they got it filled it works great.

Works as described and strobe is highly visible. Works for me.
