Your review: Standard emergency light housing and circuitry within. Sturdy metal construction, NYC approved. As expected.
Pros: Standard and easy install, good working product. 'Little' problems.
Cons: Manner of boxing leads to excessive weight placed on the test switch, (which is a pressed fit plastic device made in China), to separate internally. You must have the dexterity to re-affix the wiring to the switch, including plunger and spring assembly. It is not a difficult fix, but an unnecessary fault caused by the manner of packaging in the box. Please correct.
