nothing major.
we have pretty hard water here, it was killing one of the generic charcoal pitcher filters within a month. the filters in this one haven't had any problems by the time they are scheduled to be replaced.
a couple possibly annoying things:
- the reservoir is on the back, so it's not great against a wall under cabinets. they have a little cart you can buy explicitly to help with that, but it felt silly so I just put it somewhere else
- you can't just top up the reservoir, you have to wait for it to finish, dump it out, then refill. annoying when there's just half a tank left. I end up just trying to use an entire pitcher by dumping it into kettle/espresso machine whenever I use any water so reservoir is either entirely full or empty. afaik true of any of them that aren't plumbed in.
- don't love the fact that I'm locked in to the manufacturers' filters. there don't seem to be any third party ones available if they ever discontinue them
yeah it's kinda awful, but I like linking directly to amazon even less lol
