I got a meater block a couple years ago for Christmas. I no longer use it. After the 10th time or so one probe doesn't work anymore and the others disconnect too often and makes the app go crazy. While it still works, it is just too annoying. I think with a very thick ceramic grill, wired probes are the only way to go. YMMV.
I still just use my Thermoworks Smoke X2 with the billows. Works great, has never failed me.
