Are they prone to break easily? Do you find the input voltage readout handy?
Electronic devices don't
"break" but can occasionally fail, though the failure rate due to manufacturing error is extremely low. If anything, an EMS could
"fail" in the course of protecting your rig from any one of a number of power source anomalies ... most times it doesn't, it simply disconnects power instantly to the rig or doesn't allow power to the rig in the first place. In the unlikely event the unit is damaged in the process a Progressive unit is covered by a lifetime warranty, with a TRC you'll have no coverage after it's 1 year warranty expires and would have no recourse but to buy another new unit as TRC won't repair it nor will they sell you the parts so you can repair it yourself. :M
Voltage readout handy? Of course it's "handy", otherwise how else would you know what the incoming source voltage may be at any given time? If anything, that's one of the drawbacks of the portable versions as the monitor is part of the unit itself, visible only if you walk to wherever you've located the unit. That's one of several reasons many of us prefer the hard wire version which includes a separate monitor panel which can be mounted anywhere inside the camper where it's easy to see at a glance. It not only displays voltage but cycles through other modes as well, including error codes that will tell you what if any error has occurred.
