Bought this thermometer as an upgrade from a instant read probe thermometer and I really like it. It is on the pricey side, but the Infrared thermometer is a great resource for any chef. The temperatures are measured in .5 degree increments and reads fairly quickly; maybe 5 seconds per readout. The probe works very well and I find myself using the probe folded out at a 90 degree right angle from the main body as it keeps my hand out of the heat. It almost makes me wish the digital temp read out we're rotated 90 degrees so that when the probe were completely unfolded you could read the temp when held sideways. The infrared comes in super handy when measuring the temperature of hot water for yeast, maintaining the proper temperature of delicate butter sauces and even reading the surface temperature of foods to know when they are at a perfect temperature for serving. The infrared doesn't work well on reflective surfaces (such as a stainless steel pan) due to the light reflecting off the surface. Overall a good product that combines two temperature measuring tools that I lov
