...... They hold one year....... Then you will get a new one. Not sure if there are cheaper ones as you need replacements anyway....

My kitchen aid mixer is about 20 years old. I had a repair shop fix the original broken coupler about 10 years ago. When it broke again, I bought a $20 plastic blender which is nice and light weight. With the many DIY videos out there and replacement parts available on Amazon, I pulled out my old blender and decided to try to repair it myself. I watched a bunch of DIY videos and bought this 2-pack with a spanner. Most of the videos showed the coupler easily being replaced and a lot of reviews here say it is easy as well. My old coupler was not easy to remove. I used the spanner that came with the coupler to stabilize the screw, but the old coupler would not budge. You need to make some adjustments to get the spanner to fit correctly but it definitely fits perfectly. In the end, my solution was to use the spanner to keep the screw in place and then I had use an adjustable wrench to twist the coupler until it finally came off. I didn’t want to strip the threads of the screw by forcing it off with a flat head screwdriver (which a lot of the videos used). I also used the spanner to hold the screw in place so I could screw on the new replacement coupler. I recommend buying this coupler pack with the spanner - for me, the spanner was essential.

Everything worked as expected super happy.

It was an easy fix. I looked up a YouTube video. Parts were exact fit for my Kitchenaid Blender

Perfect match for replacement. Very quick delivery.

The shipping was quick, the product fit perfectly, and was easy to install. The tool helped to tighten and I have a spare coupling now. It is a little tricky to uninstall without the tool, but you can Youtube it for simple ideas.
