Not sure why iGrill 2 doesn’t get any love around here, but mine has been going strong for a few years with no issues. Only comes with two probes, but able to connect 4. Sure, it’s Bluetooth only, but can be paired and mirrored to any TV (or speaker if you just want to hear alerts) using airplay.
I may eventually buy a Smoke when this iGrill dies, but based on the abuse it has already sustained, that doesn’t seem likely to happen any time soon.
