Delivery:
As always fast with Amazon Prime. Packed Safely - all wonderful.
Installation:
Simply replace the old cartridge and keep the new for few seconds under the faucet.
Price-Performance:
When I go to my account and spend every week 1x 5.99 per box of water I'm at the end of the month at 23.96. When I calculate the mortgage off I'm still at about 19. Nearly 50 cost the 12-Pack and I will about 1 year, depending on usage. Use the filtered water both for cooking, my Melitta fully automatic, kettle and of course for drinking.
For me, this means a saving of about 178!
Conclusion:
Not only saves money but also time and energy. I do not have to drink market and crate dragging, and the durability of my Melitta fully automatic and the kettle Limes really extended any more.
From me 5 stars
