Good experience all around
1 - Ordering and fulfillment - excellent. Product went out same day and was delivered next day (I'm just one state away). 2 - Customer service - excellent. Fedex mis-delivered to some place I still don't know where - nothing recognizable in Fedex's photo. Constance researched while I was on the phone, shipped out again within an hour or two, and replacement shipment arrived next day. (This Fedex driver must have had a GPS.) 3 - Size of product. I read the complaints before I ordered. The complaints don't seem valid. First, the actual size is plainly stated. Second, before I ordered I measured one of the 12x12x1 filters I already had (different brand) and IT TOO was 11.75x11.75x0.75, so this seems to be a standard. Maybe not the universal standard, but filters fit the duct opening just fine.
