We broke several of these.
The latest version, the extra strong, have axle ball heads that are equally sized, meaning that the ball head at end of the ECS axle going from the outdrive is now physically bigger and more strong.
This modification have made them durable. We have not broken any of the extra strongs.
Yeah, the old 1.5mm pin ECS would often break pins and then usually mangle the ECS in the middle. The v2 ones wouldn't break the pins, but the shaft would shear off at the ball (I shudder to think about the number of those that I sheared off, almost entirely just from hitting the brakes at the end of the straight. $$$$$) The new Extra strong ones have been really solid so far. No complaints.
I've used Arrowmax ECS as well. They aren't bad for the price. Just need to flip the retaining springs around on one side so they don't accidentally pop off from nicking the chub while rotating.
The new extra strong xray ECS seem to be the best so far. Will buy again, no doubt.
