I was concerned with the negative reviews of the product. After combing over the reviews on Amazon, I determined that the negative reviews, with a few exceptions, were outliers and not indicative of the quality of the product. So, I purchased it and started testing it almost immediately upon arrival from UPS. The product works. I tested it in our Maytag oven. There were disparities between the temp on the oven display and the readings from the ET-732. The ET-732 kept fluctuating, first upward and then downward. I figured that this was caused by the cycling of the oven (it's electric). I then tested it in my kettle grill. The reading from the dome thermometer never agreed with the ET-732, and was usually higher, due no doubt to the location of the kettle in direct sunlight, intense sunlight, down here on the space coast.
The alarms work when they're supposed to work. The probes and the connecting wires seem long enough to accommodate any cooking I do on the kettle or on my gas grill. I've only tested the oven/grill probe. I haven't tested the food probe. However, when the food probe was resting on the aluminum table, it picked up a reading of 154 degrees, which sounds reasonable to me since I couldn't touch the table without getting burned, and this was before I put any lit coals in the kettle.
