Product review (5 stars): Works well along with 5-in-1 unit !
Using this with the 5-in-1 weather station, works great top upload to AcuRite and underground. Have had it a few months without the slightest problems. I also use the AcuRite app on my iPhone, works very well. Keep in mind this thing can only connect to three of AcuRite's devices, so one of the supplied thermometers cannot be used by me since I already had the 5-in-1. However, this was cheaper than buying two thermometer sensors and the base unit separately.
