Product review (1 stars): I got screwed
The product I was shipped isn't what is pictured.  It doesn't attach in the same way as the original.  In fact, it is completely backwards and won't pump water in the correct direction if I install it.  I called Aprilaire and they believe it is a knock off product.  Unfortunately, I have waited to find this out until it is past the return date.  When you receive yours, check to make sure you have the product they told you you would get.  You might wind up screwed like me.
