I got my IBBQ-4T and so far I am loving it. It seems to be very well made, withe nice probes and they are color coded, so you easily know which readout on the screen shows which probe. The app is also nice, it allows charting your cook without a lot of extra junk thrown in. I already had the IBT-4XS and it has been very reliable and accurate. Lots of times I do 2 cooks at the same time, so I have been looking for another wireless thermometer but I wanted this one to be WiFi and waterproof. I haven't wanted to spend the money for what I had seen available and then I saw the new 4T, so with my experience with the 4XS, I wanted to give it a try. I would highly recommend the new 4T for anyone looking for a WiFi thermometer.
