Product review (5 stars): AcuRite - easily assembled and good product for the money
I purchased this model after another comparable brand would not accept a signal from the outdoor sensor, even though it was property set up.  I didn't need a PhD in nuclear physics to get the AcuRite unit working. The instructions were clearly written, and it was easily assembled in a matter of seconds.  After one week, I am very satisfied.  We experience cold weather, so the use of lithium batteries is required in the sensor.  At this point the unit works well and does not suffer disturbance from other signaling devices, whether a wireless home security system or Wi Fi.
