The installation took about 30 minutes. I did the installation myself and should be within the ability of of DIY types who have experience with electric circuts, It's not rocket science but if you need a profession installer, it is a very short bit of work so it could easily be added onto some other routine service call.
The wireless transmission on this unit works flawlessly in old construction metal lathe walls at a distance of 60 feet. In fact, I can take the remote unit nearly 800 feet from the house and it still stays in contact.
Thermostat seems to be predictive and after a few day, will deliver the programmed temperatures within a few minutes of the programmed time.
Much simpler solution then popping holes in walls to run internal lines, and the multi point control is very useful.

I have a two story home with a programmable thermostat on the second floor. It was a pain to walk up and down the stairs just to adjust temperature. I ordered this product and was delivered within 3-4 days. Installation was a breeze. I am no electrician and was able to have this thermostat installed in less than an hour.

This kit is awesome; I wanted to move my thermostat (really old style, the quicksilver type) from the dining room to the living room......
... and with this kit, no wiring through walls needed. At all.
And the unit is a decent programmable thermostat; it's set to warm up in the morning, and back again when we get home from work... it is a 5+1+1 system, where all weekdays have the same program...
Honest reviews on Honeywell YTH6320R1015 - Wireless Thermostat System
After much research as to how best to deal with vast temperature variations in our one zone, multi-story condo, I found this thermostat. As stated, the thermostat includes a wireless base (which can be attached to a wall or not) and remote. The base is programmable and senses the temperature wherever the base is. The remote can be moved anywhere in the house to sense temperature in other locations (e.g. bedrooms, offices) and then can be easily set to over-ride the base and control the temperature at that remote location. This works great at night if your bedroom is far away from the base.
Because I found it hard to get product information, I called Honeywell, which has fantastic customer service. If you opt to have the thermostat installed for you, I would highly recommend using contractors recommended by Honeywell as the first several contractors I tried were suspicious of these "new-fangled" thermostats and couldn't explain how they worked.
What a great quality of life improvement! I'm already sleeping better at night!

Bought it and got it hooked up it hooks up just like any other thermostat, but the base unit goes by the furnace, not in the living space.
We put the remote in our new baby's room, and it keeps the room a perfect even temperature at night. She started sleeping much better the very night I got it working. So new parents highly recommended.
Honestly, the "outdoor" unit and the normal thermostat are still sitting on the coffee table in our living room since I can't decide where to put either one.
Only negative I think it's cycling the air on and off more often than the old thermostat did.

Update 2/24/13: The portable unit's touch screen stopped responding to touch in January. The seller I bought it from was non-responsive to my inquiries, and Honeywell informed me that the date code meant that it was made in the 42nd week of 2008!
(The date code is really simple just YYWW year/week of year. Or maybe the other way around, WWYY. I don't remember now.)
Fortunately they give a five-year warranty on this line and after mailing the broken one to Honeywell, a new one showed up on my front porch about a month later.
So if you're buying from anyone except Amazon themselves, you may want to inquire about date code, because the warranty may give you difficulties if you have problems. I still like the actual item, though. Just not the fact that I bought 4-year-old stock.
