A couple of comments:
Have a good look at the knob before you fit it. If you're not 100% happy using it, don't fit it! Once it's on, it won't come off.
To fit it, just push it on to the spindle until it stops. It should be just recessed in to the housing. It should be a tight push-fit and should not require any glue.
Honest feedback is requested please. If you like it, great. If you don't like it, why not?
Finally, please let me know what you think a reasonable price is for this, by pm if you prefer.
Thanks
