Bests & Worsts Reviews from Amazon

I purchased four different oven thermometers to test: * Ademtior Kitchen Oven Thermometer http://www.amazon.com/gp/product/B003EDY97U * Taylor Oven Guide Thermometer http://www.amazon.com/gp/product/B00004XSCA * Rubbermaid Commercial Stainless Steel Oven Monitoring Thermometer http://www.amazon.com/gp/product/B005KDEIZ0 * Taylor TruTemp Oven Dial Thermometer (from BedBath&Beyond) I tested these over a range of temperatures from 300 to 450 degrees F on separate ocasions, allowing the oven and the thermometers to completely cool between tests. Right away I noticed that the Rubbermaid and TruTemp models were junk. Both of these thermometers read anywhere from 20 to 50 degrees off from the other two. They were also slower to adjust temperature, meaning that once the oven was preheated and the other thermometers displayed the temperature, both the Rubbermaid and TruTemp thermometers continued to adjust their readouts. The Taylor Oven Guide thermometer was off by about 15 degrees at each temperature setting (compared to the Ademitor and my oven setting, but since the readout was consistently 15 degrees off at all temperatures, it’s clear that this resulted from a misaligned glass tube. Fortunately, this is easily adjustable simply by sliding the tube to the left or right as necessary. Between the Ademitor and the Taylor Oven Guide, I think the Ademitor is slightly easier to read but the base is a bit too small, making it easy to fall through the oven rack. The Oven Guide has a much wider base so it stands up nicely.
