Worth their weight in gold.
Adds a level of forgiveness and latitude when it comes to getting the lead rods straight. Top tip - drop a quarter of an inch ball bearing in once you have attached it to the motor. This means you can bolt in the lead screw without its weight pressing down and compressing the coupler, negating its advantage. Very happy with the pair I have on my ender 3 v2.

What a difference!
By far the best mod for the money I've done to my printer. I've had ongoing issues with the Z alignment on my ender 3. No matter what adjustments I have made I get binding at some point during a large print. Installing this with a ball bearing mod (see youtube Alex kenis) has made all of my problems go away. I have never had such a smooth print since installing it. For the price, I would highly recommend it. Just don't forget to put a ball bearing in to take the gantry weight off the coupler. 10/10.I'm not sure how long it will last, but you get 2 in a pack, so I'm not overly concerned and with the addition of the ball bearing I'm sure I'll get a while.

Overpriced
Painfully slow delivery for such an overpriced item. These are exactly the same (the part number on the packaging confirms this) as the ones you can buy 7 of, for less than £7, with two suitable hex keys supplied. With fast delivery.

Very good quality.
Great product, I've put these on my printer. Alot better than the ones what came with the printer. Very good grip on the bar. Definitely would recommend to anyone.

well worth buying
well worth buying these for piece of mind that the stock plastic tubing mounts aren't warping or slipping

Good enough
Finally eliminated all my z axis problems. I recommend this product for anyone that has z wobble and loss of resolution

Cured the Z banding on my Anycubic I3 Mega.
Big improvement on the Z banding (rough vertical prints) issues on the I3.
