I've never seen rating categories for "transparency" and "thickness" rated like this before. Well, I'm giving it 5 stars simply because it falls into the "I didn't think this part was available" category. As mentioned by others, most exploded views show parts as part of an assembly. As mentioned, watch the YouTube video (search for "blue cyclonic fixer"). You only need to grind one of the "sections" since the other will start first. I turned it step by step to make sure I didn't make it too short. I used lube as shown and it takes more effort than I expected. But now it works very well. And yes, it's expensive for what you get, but worth it in my opinion. My wife was unhappy that I had to use gorilla tape to hold it together after I broke it and it worked.
