The outdoor unit consistently reads .3-1 degree higher than the indoor, even when they're standing next to each other.

My unit's outdoor sensor stopped transmitting less than 24 hours after I turned it on and it hasn't worked since. I live in northeast Texas--hardly an extreme climate.

It's been a week and the atomic clock still hasn't successfully connected once--not even when I stand in the front yard to get a clear signal.
Also, the backlight/snooze button whines like a dying mosquito for a few seconds when activated.

Besides those things, the alarm seems to work fine and the temperature measured is fairly accurate and consistent. The ice alarm is a neat idea: you can set it to wake you up early if the temperature is below freezing. I just don't have much use for it, living in Texas.

Bought this unit to replace a different brand in which the outdoor sensor ceased to operate. Yes, we went through all of the suggested steps to get it to reboot, wait ten minutes with no batteries, add new batteries in the correct steps, wait another ten minutes. Nothing worked.

So far this unit is working fine. I believe the outdoor temp is off by about a degree or two but that is no huge deal.

When is someone going to make one of these things with an outdoor sensor that does not have to be protected from the elements?

This thermometer replaced a cheaper model made by another company which had stopped working after two years. This device ws easy to set up and has worked perfectly throuigh extremely cold and wet conditions while the outside thermometer is mounted on a tree. It is easy to read and looks good too!

This unit has everything going for it, feature-wise. I bought it in defiance of some of the negative reviews it has received.

After having used it for a couple/several months now, my report is: It started off fine. But after about a month, the indoor display unit lost contact with the outdoor sensor unit. Translation: Indoor temp displayed; Outdoor temp blank.

So I followed the manual instructions and got the two units to reconnect. 10 days or so pass. Same deal. Then another week... Same deal.

Am I going to have to manually reconnect these two units every two weeks for the life of the product? -- being, I would think, at least several years? The two units are only separated by about 25 feet. That doesn't seem reasonable, to me.

It's too bad. So many other things are right about this product. But one of its core functions seems to be intermittent.

I would send it back for a refund, but it's not worth the bother. I suggest you save yourself the expense and the bother.

I bought one of these for myself and gave others as gifts. Works great no problems. Accurate and easy to use. The people who received these as gifts loved them. Even in extreme temps working fine. Use lithium batteries and follow directions and you should have a good experience.
