I had submitted a review earlier (as follows). However, I've become very disappointed with the operation of this unit. Specifically, it stops showing the remote temperature FREQUENTLY. Nothing wrong with the remote. I remedy the problem by removing one battery in the main unit, then replace it and wait for it to correct itself. ** end of edit ** Original review follows and still applies. RR
I installed the unit just after the Denver Christmas 2006 blizzard. I used standard batteries in the remote but was still able to read -11 deg F. Later, the unit stopped transmitting (see other person's review). I replaced the remote batteries and it has worked fine since then. I might go with lithium batteries next time.
The real drawback, in my view, is the smooth, curved display cover. It reflects light from all directions and makes it difficult to read unless you move around or move very close. The product would be better with a flat display cover and/or an etched cover (to reduce reflection).

I like this item except it regularly stops transmitting the signal from the remote sensor for a period of time--usually several hours. Then it will start again. Perhaps it doesn't like to get cold!

I am using this unit to monitor the outside temperature. I like it so well that I bought a second unit so I could see the outside temperature at too different locations. I mounted the remote unit outside and was able to see the remote unit from the other side of the house. I put two AA lithium batteries in the outside unit so it will continue to work in the frigid winter temperatures I am expecting (it worked). I do get some dropouts of the sensor from time to time. Simply pushing the down-arrow to have the base unit scan then finds it again.

The atomic clock feature worked without problem. Having a reliable time source is rather nice. Setting the timezone is a little tricky (the only part that the atomic clock can't handle by itself) but only needs to be done once (maybe after each battery change?). With day of the week showing hold down the up-arrow button; every couple of seconds a new segment of the map icon will highlight.

When the base unit batteries get weak it can cause it to start dropping the remote units so consider replacing those before deciding remote unit is defective.

I bought this for my hubby for Christmas and when he opened it, he loved it! He's an engineer and somewhat of a 'techy' guy so it was a nice surprise (not something he had asked for).
He placed the outdoor unit just outside our front door, covered by an open porch and it worked very nicely.... for a month anyways....
We've had some bitterly cold days/nites here in Illinois and it is no longer transmitting a signal to the inside unit. He replaced the batteries, fanagled it a bit, but it is still not transmitting to the indoor unit. The atomic clock works and the indoor thermometer works, but it doesn't tell us the outdoor temp anymore. What a HUGE disappointment!!

I was initially satisfied but now it is essentially not working. FirstI lost the remote temp and now the main unit is do dim you can't read it.
