I posted my take on my collection of ThermoWorks thermometers on the Thermometers Accessory subforum. I am not sure how often the forum is visited so I thought I would mention it here.

I address the following:

ThermaPen MK4
ThermaQ
ChefAlarm
Signals
Industrial IR-IND

Comparing my ThermoWorks Thermometers

Believe it or not the 600D pocket thermometer is my most often used Thermoworks product and the item I have most gifted to others.
