Been running these for a couple of weeks now. We get a lot of road salt and grime out here, but these whale tails are holding up great. No sticking, no rattles on the highway. The handle is big enough to grab even when I'm wearing my thick winter gloves. If you're building a work truck and want it to last, these are the ones to get.
Lock installed, switch smooth, surface polishing is so good.
