Screwed this onto my existing shaft expecting a little wobble, but the connection is rock solid with zero play. That extra 100mm really changes the balance for the better, and the build quality feels like it'll outlast everything else in my kit.

The extra 100mm makes a noticeable difference on my longer reach setups, and the build feels solid with zero flex. Installation took just a couple minutes and it's been rock solid since.

Does what it says and adds the extra 100mm of reach I needed, but the finish scratches easier than I'd like. It fits the shaft fine and feels solid enough, just not the premium feel I was expecting at this price.
