Product review (2 stars): accurate and easy -- when it works
Got this installed and set up in less than 5 minutes. Temperature readings are accurate and easy to read. My transmitter is about 20' from the base station, but I tried it in various locations up to 50' away, and still got good readings.

There are other devices out there that give more info, but I intentionally avoided that -- I think their screens are too cluttered and confusing. Just tell me the temperature and humidity inside and outside, please. (This will also tell you historic highs and lows, but you have to push a button on the back, and mine is wall-mounted.)

I did spend a few extra bucks to get lithium batteries for the transmitter (not the base unit), because the manufacturer recommends them for really cold temperatures, which we occasionally get. Plus, the lithium batteries last a lot longer than alkalines.

Update after 5 months: The remote sensor stopped working. Chaney Instrument sent me a new sensor (took about 2 weeks), but that one doesn't work either. I've contacted them again, and they want me to send both sensors and the base unit back to them, in Wisconsin, for repairs. I guess that meets the terms of their warranty, but I'm not sure it's worth $10 in shipping costs to get it to them, since a) I paid only $25 for the unit new, and b) lots of other reviewers report problems with the sensor. I may just buy a different unit -- definitely not Acu-Rite.
