- Reviewed in Canada on August 8, 2024Verified PurchaseThese work great. My only caution is to make sure you line it up right before you stick it on the window because once it’s on it is not coming off. The first one I put on is a little askew but I got the second one on straight. Live and learn.
- Reviewed in Canada on February 5, 2025Verified PurchaseThis thermometer is very hard to see. Furthermore it is not accurate.
Would not recommend
- Reviewed in Canada on December 3, 2024Verified PurchaseLove how easy it is just to stick on the window and how easy it is to see the temperature. Keep in mind that it is on glass so when the sun hits the window, as it does in the winter months at my home, the temperature is not accurate, obviously. The picture above was taken while the real outside temperature was 40 degrees.

- Reviewed in Canada on July 28, 2025Verified Purchaseawesome outdoor thermometer - easy to mount on the window, we mounted ours on our kitchen window by the coffe maker so while we get our morning coffee we can see the temp outside and it is very accurate - I see in the reviews there has been some problems when it's very cold but I am on the west coast and we don't get very cold so thinking for me there won't be any issues

- Reviewed in Canada on January 2, 2025Verified PurchaseThis thermometre is about 5 degrees off of the actual temperature, so it is a completely useless product. Do not buy.
