Update on my ET-732:
I got the ET-732 because it has much longer range than my ET-73 has.
The second time I cleaned the meat probe & cable, the wire covering pulled out of the probe.
I called Maverick, and told them what happened, and that I was cleaning it the same way I have been cleaning the original probes on my ET-73 for nearly 2 years.
They said, "No problem, send it to us with a note & your address, and we'll send you a new one".
I also got one of each probe for backups, because I found out the ET-73 probes don't work in the ET-732 unit.
