Product review (5 stars): Great product! Great price!
This redesigned fill tube was easy to install and has been working great. The last few inches of the top of the tube (which is facing down in the photo) are cut away, which reduces the tendency for ice to build up inside the tube over time. I should note that ice accumulation in the tube can also be caused by a slow leak in the water valve, but I had already replaced that, which helped but didn't eliminate the problem completely. This new fill tube seemed to do the trick.
