Rated 2 out of 5 by from Not ready for prime time. I really wanted to love this. I was excited when it came out since having software defined radio lets you add features and upgrades. I installed this about a year ago on my sailboat. My boat is in Florida, I am in Colorado, I use this to keep track of things, particularly voltage since sometimes the yard loses power and I don't need the dehumidifier running off my 12v batteries. Some observations: Sometimes the monitoring goes out. Sometimes it's because they screw up an update and the monitoring is just flat out broken. This has happened twice. Once it was for a couple of weeks. Sometimes the unit just goes offline for no apparent reason. They tell me I need to cycle the power to it. Guess what? I'm 2000 miles away! Somehow they don't understand the remote part of remote monitoring. This part is infuriating. When I contacted them about it they said it's because my voltage dropped below 12v. It hasn't, I have the logs from my Victron devices to prove it. It never goes below 13.4. In an attempt to troubleshoot this I reinstalled the monitoring app and now it doesn't recognize that I have a monitoring subscription. It thinks I'm a free trial user. Another support call required. The wireless handset lasts about 7 hours before you need a charge. That's not long enough, it's just enough for it to die at nightfall so I had to pay for a wired handset at the binnacle so I could still use this if I'm out for more than 7 hours. These handsets are ridiculously expensive. At this point I'd return it if I could and buy something boring like an icom, or 3 icoms, for what I have invested in this. When it works it is wonderful, the DSC calling works great, the remote speaker is very nice, the ability to see ais on a little plotter on the handset is great when in the intercoastal and you're trying to figure out who is passing you. Seriously, the UI is very well done. Unfortunately the inconsistency in other parts of the package means I'm troubleshooting more than I want to. It's not quite 'built in someone's basement from a raspberry pi and an android phone' but it's not up to the standards of good marine equipment either. Somewhere in between. If you like futzing with this stuff maybe you'll love it. I just want it to work.
