Pros: These switches are very durable, have a very nice feel and have a distinct click when turning on and off. The lights are really bright for car use. When turned on, they cast a blue hue into the cabin at night. Luckily I put them in a compartment that can be opened or closed while riding. Cons: The supplied cable plugs do not fit. Upon inspection, the connections in the blue connector are misaligned. The flat blades that come out of the back of the switch are single-sided, but the corresponding slots they are intended to insert into are rotated 90Λ, so the connector cannot snap into place. I ended up having to splice and solder every connection. This is great if you will NEVER need to replace the derailleur, but if it fails then snapping the connector into place is a lot easier. Aside from requiring you to do a little more work to use these switches, they're great. Without the mentioned problem they would have gotten 5 stars.
