Bests & Worsts Reviews from Amazon

The evening it came, I gave it a try. The temperature is way off.. on both ends of the scale. Using a digital cooking thermometer, I measured hot and cold water running at the tap, the BAFX was at least 10 degrees low on the low side and 20 degrees off on the high side. THen I measured some copper heating pipes. I have two loops that have input and outflow themometers .. input was about 160 degrees on both supplies. The BAFX indicatred 110! Then I measured the supply to the (zone) hot water heater. The BAFX reported 82 degrees, yet, I could not hold my hand on the pipe.. it must have been much higher than 82!! Returned to Amazon the next day. PART 2: BAFX Customer support emailed me. If I was interested, he would arrange to ship me a new unit. If I liked it, I could keep it and pay for it, if not he would include a return pre-paid label. I was impressed with his support, so I agreed. I've had it about 2 weeks now. It works just as described and correlated very closely with the other (kitchen/room) thermometers around the house. Though the first one failed, with good customer support and the second one working, I would recommend this to anyone interested in one.
