Product review (4 stars): I hope this 3rd one is better, but it looks the same as the first ...
The original part lasted more than 5 years.  I replaced it once but that one lasted about 2 years before a piece of the plastic screw broke off and I found it in my iced drink.  I hope this 3rd one is better, but it looks the same as the first two.  Fortunately it is an easy install and YouTube videos cover the steps needed.  Just take your time.
