I used to either under or over cook meat on the grill... since I got the iGrill.. that never happens!!  EVER... Consistently the meat I cook on the grill is cooked perfectly... I couldn't be happier and now I don't keep lifting the lid to see how the meat is doing... usually about ½ way through.. I go lift the lid and turn over... with the 10 degree alert that the meat is almost ready... I'm right there waiting and BAM... done to perfection.  

my only con... it is bluetooth.. so keep your phone within range... but when you do go out of range (and I do frequently).. it reconnects with no problem.
