Product review (2 stars): Item not exactly what I ordered
Like the last few reviews, I received a MWFINT filter instead of the listed MWF filter from the seller (Seneca River Trading). Box said installation instructions would be inside, though I didn't find any. (Not that it's hard to install, but I hoped the documentation would explain if the MWF could be replaced by MWFINT).

Judging by the earlier responses, even if the seller's response was just a form letter, they should have included a note with the shipment. Hard to do when your shipment is merely slapping a mailing sticker on the actual product box!

Come to think of it, this review should be about product, not about the shipper. Be sure to leave feedback about Seneca River Trading under seller feedback.
