Filters came fast; love the fact that I can still get them on Amazon, otherwise, the filtering device itself would be a waste of money.  Just wish changing the damn thing was a bit easier to do and that the water filtered faster.  Perhaps that's why they didn't gain the popularity they were hoping for.  No matter, I'll keep getting them from Amazon and this is a great, econimical buy to boot...
