The IGrill is a nice unit and very comparable to the ET-732. I like that you don't have to carry a receiver with you seeing how all bluetooth devices work with it. The droid app is new and not quite as nice as the apple one. The Thermapen is a faster unit than the PT100. I own both and use them both frequently. The PT100 does has nicer options on it like a rubber outside for drop protection and backlit display for night time use.
