RoadPro Accessory Power Editorial Review
The RoadPro RP-129 Heavy-Duty SPDT Relay has inspired mixed reviews among its users, particularly regarding the functionality described in its title. While some customers appreciated its performance in specific applications—like using it for a momentary pushbutton high beam light selector on a motorcycle—several users were disappointed by the misrepresentation of its capabilities. Many reviewers point out that although the product is advertised as a "latching relay," it operates more like a standard relay, which can be misleading for customers looking for specific functionalities associated with latching relays. Overall, while the RP-129 is noted for its robust Construction and ease of installation, users emphasize the importance of understanding its true nature as a relay rather than a latching relay. This discrepancy significantly affects customer satisfaction, as expectations do not align with the product's actual performance. **
