I like OXO products for their generally well-designed traits. Unfortunately, this oven thermometer is the exception to OXO quality and design. The thermometer is fairly accurate in its temperature reading, and the temperature numbers on the dial are easy to read when backlit by the oven lightbulb (if you have one). What makes the product totally flawed and worse than useless is the ridiculously idiotic mounting mechanism -- two metal clips on each side of the device, which are so short, they won't even lock onto my oven rack, and keep making the thermometer fall off the rack. It's the essence of stupid design, just plain stupid. Also, when the thermometer is in place (assuming that you can actually get it to stay in place), it takes up several inches of space on the rack, preventing you from sliding an oven pan all the way towards the back of the oven.Go with a hanging thermometer instead and save yourself a lot of frustration.
