Query: Last Pur I will ever buy

This is my second one of these. The first had such a low flow of filtered water I got tired of waiting 10 minutes to fill a glass, so I took it off after about 5 filter changes. My current unit (different city) sprung a leak in the usage indicator window (which never worked no matter how long i used a filter). Now, water either snakes down the side of the thing and back into my glass, defeating the purpose of a filter, or it shoots out, spraying whoever is using it.Aside from that, it doesn't seat very firmly, so you'll have to tighten the fitting about twice a week. Lastly, a piece over the faucet fell off. I slide it back on, but it comes off eventually on it's own again.This thing's junk. The filters are expensive and hard to find unless you order online in large quantities.
