Query: Cheap plastic

Seemed shabbily made of plastic, hard to open and fragile with the possibility of cracking when changing the cartridge - was big and bulky on the faucet - and flavored water? Plain water was what I was going for, I wanted a filter that removed taste, not added it - I returned the product and got a filtering pitcher which does not take up so much space and works like a dream. No flavors in this water.
