Went through several of these before I learned my lesson. The casing after 3 to 4 months crack and water begins squirting all over the place. Though the filtrated water was good I just can't afford to continually replace units every 3 months.
Bad product:
As many other reviewers state - the thing leaks upon installation.
If you want a faucet filter, get one under the cabinet or a whole house.
Another option is the Brita, which is what we did after this leaked.
I even got the stainless one, which is just the cover - it's all plastic inside and basically junk.
Leaks like hell !!!!:
We've used 3 of these and each and every one of them leaked like hell after a couple of months. At first I just thought we got unlucky, but after three what can I say?
Filters well, easy to install and use, not durable:
This was a replacement for an earlier instance of the same filter that we previously owned. Works great, but it started falling apart after a little over a year.
