Product review (5 stars): Very easy to install, works great
Was pleasantly surprised at how well it fit my machine, and how easy it was to install.  I just used a flat head screwdriver to pop off the cap on my washing machine tub spindle.  Then I snapped this in the place of it.  Took 30 seconds and minimal effort.  I've used it at least 50 times and it dispenses just fine every time.  I am beyond pleased - worth the money to add a fabric softener option to my simple washing machine.
