I want to like these more but depending on your bar, they can be a real bitch to clamp down.
On my Texas power bar, it's a workout getting them to close. My axle, elitefts ssb, rogue power bar, not a problem.
Price wise, I got them on sale, I think 2 pair for either 30 or 40 bucks.
The magnetic feature is the best part. Stays on my rack with no issues.
