If you don't have one of these thermometers, you are REALLY missing out (not to mention making things way too hard on yourself). Forget about guessing how much longer until the Thanksgiving turkey's cheap thermometer pops up. Stop cutting into your roasted chicken or steak to see if the middle is done yet. With one of these bad boys, you just set the alert temperature on the display unit, stick the probe in the meat, put the meat in the oven or on the grill and sit back and relax until the internal temperature reaches the desired setting.
Go ahead and treat yourself to something nice...you (and your dinner guests) deserve it. It'll be the best $20 you'll ever spend on a kitchen gadget.
