I have the 30 amp version of this:
click here.With the Blue Tooth technology, the read-outs are shown on my phone. It also sets off a warning when you reach limits. For example, if I reach 30 amps, I get a warning before it trips, or the breaker pops. It's quite interesting to turn on an appliance and watch the usage change.
The 50 amp will show the usage on each leg.
I ended up getting a Progressive portable for 50 amp service, only because I bought the 30 WatchDog 2 weeks before we knew we were going to be getting the new 5er. I decided to keep the 30 amp Watch Dog since I don't have a 50 amp plug at home yet and have to plug into 30 amp anyway. It works pretty nice. When camping with 50 amp service, I'll use the Progressive at the campground. I'm planning on getting a 50 amp plug installed at home, soon.
