Product review (5 stars): Amazon sells genuine ones, Appliance Cove sells bootleg ones
Six months ago I ordered one sold by Amazon and it worked great with my fridge.
A week ago I ordered another one and did not notice that is not sold by Amazon. At first I thought there is no big deal, it was prime eligible so it arrived on time.

I received the package and I noticed something is not right when I tried to replace it. The two filters do not look the same.
So I immediately went to Home Depot to buy another one to see which of them is bootleg.

I have three photos here:
Photo 1 - the boxes:
Left - from Appliance Cove, Right - from Home Depot.
Left one is a bit smaller. An extra label is there hiding the original barcode. The barcode on top does not match anything from Google search.
Right one is a bit bigger. Search the barcode on Google will return you it is GE MWF water filter.

Photo 2 - the filter:
From left to right: from Amazon, from Appliance Cove, from Home Depot.
You can notice that the print of the center one is worse than the others.

Photo 3 - the filter again:
From left to right: from Amazon, from Appliance Cove, from Home Depot.
Again the center one does not look same as the others. The align arrow does not align and it is shorter than the others.

Clearly the one from Appliance Cove is a bootleg product.
