Oregon Scientific EMR812 Wireless Thermometer

Amazon.com Review:
Conquer the limits of space and time with this cable-free radio-frequency thermometer from Oregon Scientific. Tuning in to as many as three remote units at once, this thermometer helps monitor the four corners of your kingdom from one base unit. The kit includes one remote sensor, which can be stationed up to 120 feet away and sends signals every 30 seconds. The main unit's LCD screen lets you assign a channel to each remote, and then scroll through the menu as necessary. You can also set temperature range limits, program alarms, and recall recent highs and lows at each location. A temperature-trend icon reveals whether temperatures are rising, steady, or dropping. The thermometer's base-unit range is 23 to 122 degrees F, while the remote sensor runs from –58 to 158 degrees F. Both units feature an optional Centigrade scale. Designed for the desktop or the wall, each piece of equipment requires two AA batteries. --Emily Bedard

Rating : - Negative experience
NOT SO GOOD TRANSMITTER & RECEIVER WORKED FINE FOR ABOUT A WEEK. THEN TRANSMITTER SHUT DOWN. NEW BATTERY, TWICE, MADE NO DIFFERENCE. UNABLE TO FIND A PATH TO CONTACT AMAZON. DID FIND A PATH AT OREGON SCIENTIFIC WHICH PROMISED A RESPONSE WITHIN 4 DAYS. BEEN 2 WEEKS NOW AND NO RESPONSE FROM THEM. RECEIVER STILL WORKS FINE BUT GIVES ONLY INDOOR TEMP. TRANSMITTER WAS IN SHELTERED SPOT AND SUFFERED NO DAMAGE OTHER THAN ZOMKING OUT.

BAD EXPERIENCE WITH BOTH COMPANIES
