HORRIBLE! DO NOT ORDER FROM THEM!
I made a mistake and did not check the reviews of this company before placing my order. I ordered 3 filter cartridges and received only 2... I've been calling the phone number they have on the site, but forget it - NOBODY ever picks up and even if you leave the message, they NEVER call back... I've been shopping on internet for years and this is one of the worst experiences ever!
Do yourself a favor and do not waste your time & money and order somewhere else...
