I have a love/hate with the last decade of rhinos. We use them with blue chart for communication between boat and skiff as they do a frs system like marine ais. Works good in the fog...well when they work.
Currently have some 755ts. Ran 655ts until they weren't worth fixing. Hopefully the 755s are better, we always had a spare of the 655s as they broke sometimes faster than the warranty could fix them. Mostly mic related issues, but we lost a screen or two and a transmitter. Garmin was always tops about fixing them even out of warranty they fixed them for reasonable price. Cutrently they are one of a kind, so we keep buying and fixing them. The old garmin hand and car units were like Nokia phones.... the rhinos aren't.
*Went and looked in my pelican of radios, looks like we lost a ptt button on one this summer and it needs sent out. That was always the week link.
I guess the tldr is they work but break, but no one else makes anything equal so....
