Product review (3 stars): Why replacement pack is not cheaper than this?
I have two issues with this products.

1) Simply overpriced. I should have started the search for alternative product earlier before due came up.

2) Why the replacement pack cost more than the starter kit?

I see the manufacturer's logic (to attract new customer who wants to give a try) but who on earth would willingly pay this "discounted" starter kit unless your fridge don't designate it? I myself am not the first time user and I had to buy this starter kit because I do not spend more money by buying replacement pack only. Hey Whirlpool, why don't you lower the replacement pack price and avoid creating unnecessary waste (holder and attachment). This type of marketing technique only makes your loyal customer unhappy.
