Product review (2 stars): Like someone else said
Like someone else said, the filters came FOLDED in a small envelop.  For this price, they could have at least put them in a regular sized envelop.  Shipping was one day late but I don't necessarily fault the seller for that.  The product is as described but I really feel ripped off.  I mean, come on, twenty something dollars for 4 of these and on odd-shaped filter?  I bought them because I had no choice.  I couldn't find them anywhere else but I will try making my own out of felt next time.  For this price, there should have been a box full of them (at least 10 to 15) and they are paper thin, as one other reviewer pointed out, and weigh next to nothing, so that sure saves the seller on shipping costs.  So, my main complaint is not with the product, per se, but with the cost of the product.  I can't see how throwing in a few more filters would hurt the seller (cost-wise) and would make for happier customers.  On a side note, I have found that using a lint brush, after each setting, really prolongs that life of these things.  However, using the lint brushes gets expensive too.
