You have to have this, or the wine cellar does not work correctly, but it is too expensive.
Once I figured out how to get the old one out (from the inside, using a diagonal pliers), replacement was simple. I've owned my EuroCave for over 3 years now, and have had no trouble whatsoever. I love it. That said, this required consumable is WAY TOO EXPENSIVE. I feel like I'm getting ripped off. Hence 4 stars instead of 5.
