Product review (5 stars): Reliable and accurate
I got this unit to monitor the temp and humidity inside a greenhouse here in New England. Its only been in service for a few weeks but so far its proven to be reliable and pretty accurate although its not exposed to the weather. If I were to locate one outside of the greenhouse I'd put it in a clear plastic bottle with the bottom cut out just to keep the rain and snow off it.

The sensor is located inside a greenhouse with polycarbonate panels and is being read from about 60 feet away through the house walls. I compare the temp/humidity readings with the local ones from Intellicast and Weather Bug and, in as much as neither of them ever agree, the reading from the AcuRite is very close. I attribute temp/humidity variations to differences in location and to the fact that the sensor is inside the greenhouse.

Great little unit for the price. Hopefully it will last.
