One of its standout features is the integrated LED light, which provides illumination where it's most needed, making nighttime operations easier. The jack is also praised for its ease of installation and high reliability, backed by a one-year warranty and responsive customer service. However, some potential drawbacks include its weight of 23.1 pounds, which might be a bit cumbersome for some users, and the need for hard wiring to a 12V DC power source, which could complicate installation for those not familiar with electrical setups.
