    • Work great with a E3V2
Replaced the ones I had on my e3v2 for my dual z as they seemed to be defective and these were a hell of a lot better. Work great, definitely recommended.

    • Meh
Works alright, but the small end turned out to be smaller than listed so I had to drill it out myself.

    • Quality couplers
It comes with two Allen wrenches. 5 x 8 mm couplers.

    • Eh, not the best
One broke on me. Not under any pressure. Snapped off right in the middle. Entire thing split. Not faith in the others. Good luck

    • Bad QA/Manufacturing
The primary issue I encountered with every coupler in the pack was that the holes were drilled off center, which was the main cause of the problems I experienced. It's worth noting that the shape itself was fine, but the machining quality was incredibly poor, resulting in noticeable burrs. In my opinion, these couplers should be removed from Amazon due to their subpar quality. ... show more

    • Sloppy
Every one of these in the pack had an off center and angular bore. The point of a flex couple is to mitigate eccentricities, not exaggerate them, which is exactly what these couplers did. They are really that bad. Not worth the headache.

    • Very Helpful - Work Great!
Awesome way to help with Z Rod inconsistencies. I was afraid these would push and pull, but they just flex as intended. Nice to have a handful just in case. I've tried a few just to see consistency, and so far, none of them have broken, threads for the lock nuts have been clean, and they do their intended job well. ... show more
