Easy setup
Setup is so easy, only took minutes. The first wireless location in my garage (during setup) worked just fine. The final location outside my home took about 5 hrs for the pairing. It is only 2 days now and the pairing is working just fine. I had an older Weather Channel model and setup use took so many steps, this Thermometer is great.

Pretty nice little unit. It's easy to read even without the light. Seems pretty accurate. Waiting to see how long batteries last.

Great indoor/outdoor unit.
We have had this installed for years now and it still works perfect. We have it in the master bathroom so we know the temp outside. Batteries last forever and it doesn't use the 9V like the older units did. Its great that it doesn't bc who have 9V batteries waiting to be used? The contrast on this is amazing. When it starts to get weak, its time to change the batteries bc it will be dead in about another month. The outside batteries last us over a year. We replace them every fall so they're strong over the winter. If you need a remote thermometer this is a great selection. We would buy this model again.

Very nice and easy to read and operate.
I bought this for my mother who is in her mid 80's. It is very easy to read for her and accurate. I will buy more in the future.

The thermometer malfunctioned after two months and no response from the seller
I purchased this thermometer in January 2026. It worked fine for 2 months and then the digital reading malfunctioned. When it is 65 degrees, the thermometer reads 5 degrees. If it is 42 degrees, the reading is 2 degrees. I requested a replacement from the seller. A week later.......still no response. There are plenty of similar thermometers available at Amazon. I will be choosing a different product and seller.

Sure!
Purchased for mother that struggles with seeing displays. After many trials of different products, this was the best one by far. Display is large and easy to read.

Great piece of tech. Simple and intuitive to set up. I used velcro to attach the external sensor under our front door awning, which works well. All good so far. Recommended.
