I've only used my ET-732 4 or 5 times, with no Problems. I hadn't read anything about probe issues. I'll see what happens as I use it more. I'm very careful when running the probe wires through the hole in the smoker and when washing them. I think mis-handling is probably how most thermos are killed. I know I've done it to 4 or 5 cheapies, that's why I thought I'd try the maverick. As for the range... Unless you're running to the corner store to get more adult beverages, I don't think you'll have any issues. I've walked to my mailbox (70 - 80 yards away) and still had a signal. The only time I lost a signal was when I had the receiver next to my computer. I picked it up and walked about 10 feet away and it re-syncronized.
