A few things I found. The Klein RT250 outlet tester can pick up issues like only the hot wire hooked up (open ground and neutral at the same time) where a model like the RT210 will display no lights and make you think the circuit is dead. Measures voltage. Measures trip time of GFCI outlet.
Still trying to find if the RT250 can pick up a neutral and ground reversed issue. The RT210 cannot.
It's always a good idea to pair one of these with a non-contact tester for safety.

May still return it because I want more versatility/information, but just a heads up to those who did the same.
Pros:
- Clear display
- Backlight for dark areas
- Also checks voltage
- Foolproof correct/fault lights
- Actual faults listed on screen
- Built-in GFCI test incl. trip time
- Light covers arent loose inserts that fall out like cheap testers
- Display holds for some seconds when you pull it out. This means you can test a socket in a hard to reach/read position and then move the unit to somewhere more accessible to read the result.
Cons:
- No afci test (arcfault) but most at this price don't have one either.
- Klein sell a combo tester/breaker tracer tool and unfortunately this unit doesn't generate the breaker trace signal for that tool, even though every other aspect of this unit is nicer.
Well worth the asking price here.
Used mine last month to diagnose a random open neutral that killed an outlet.
