What Do You Think of THIS ONE?
OK, so I caved and went for the new Thermopro TP620 thermometer. It was kind of the same "I wonder" thing that led me to buy way too many stainless grates so I could do the comparison study a couple years ago

. Still, it was regularly $49.99 but currently $10.00 off. Throw in some Discover points, and I only paid $10 to satisfy my curiosity. This new thermometer is clearly in the same family as the TP19H that I already had and like very much. With this new model, they addressed a few minor issues while bringing together the superior thermocouple sensor of one of their other designs, with the strong positives of the TP19H.
First, the packaging was very nice, becoming of a more expensive unit. They even threw in a small screwdriver to open the battery door which, like the TP19H, is lined with a rubber seal. This unit is advertised as totally washable in running water. I think the AAA battery is a great choice compared to those round batteries. I recommend using Lithium batteries to protect your investment.

The display is a bright LED readout. Whether you like it better than the yellow backlit version on the TP19H probably depends on your taste. In my view, the switch to red and black is a lot more stylish. The Thermoworks MK4 seems a little bland to me, but I do really like that they offer a whole array of colors. On this ThermoPro, it is a take it or leave it proposition.
This new model has a slightly longer needle; the "no slip" grip on top is a nice touch. The opening to hang up the thermometer is improved and now larger on this new design, but both of these units have built in magnets which can be very convenient.
Here are both the TP620 and TP19H in comparison:
I hope to put this new unit to the real test soon.
ANYBODY COMING TO THE UPPER MIDWEST MEET HAVE AN MK4?
If so, please bring so we can all compare. I will bring both of my ThermoPro units.
A FINAL NOTE:
I am also the owner of a Thermoworks Smoke and their Thermopop. Both are extremely fine units.
I absolutely LOVE my Smoke! Thermoworks is one very fine company and a supporter of TVWBB. But, as Chris mentioned, that doesn't mean we can't compare other products and make the best decision for our individual situation. I like experimenting and evaluating as objectively as possible. I appreciate that ThermoPro seems to be trying to be more than just an importer of "off brand" junk but rather to be a friend of serious BBQers like us. Their most recent products seem to be very competitive, and it could be argued in some ways are raising the bar in style and construction.
