I like my Smoke X - it has great range, 4 probes, and if you ever want to hook up a blower f0r ATC you can do that too. Expensive, but worth it. Like a few others on the forum, I prefer to run without a smartphone app.
Also, Thermoworks customer service is really good. I had an issue with an old thermapen it had a loose connection in it for years and I had to wiggle the probe end to get it to turn on, and then it finally quit working after about 5 years. I called and asked if they could repair, they said they could for about $50 or so, but for a little bit more $ they gave me a deal on a new one.
Really can't go wrong with any Thermoworks product in my book.
