Yeah for $14 thats a no brainer
The old owner added the meters, but the wiring could have been better, hopefully he doesn't find this thread
The wires were not very tight in the meters, and the hot side was wired to the wrong side of the 240v breaker, so if it ever came loose, it would be hot 120v in the panel with no short circuit protection. Glad I noticed that and fixed it
The meters are good, but they have no decimal on the frequency, which would have been nice. Good for a quick glance to see current though
