What's good
- Self-test means a dead GFCI announces itself instead of failing silently
- Feed-through protects the rest of the circuit downstream
- Slim body fits crowded boxes
What's not
- This specific model is non-tamper-resistant — where the location also requires TR, use Leviton's TR self-test variant
- 2-year warranty is shorter than the spec-grade duplexes above
Our verdict
Every pre-self-test GFCI in service is a coin flip on whether it still protects. Replacing decades-old units with self-testing ones is one of the highest-value ten-dollar upgrades in a house; just match the TR variant where code asks for it.
