Happy with Shield always!
The filters are easy to replace, the only concern I have with this company is that when I approached them with a concern I received no reply. This is why I cannot give full marks.
Luckily for me I had a plumber installing other products, as even he had a bit of trouble following the instructions. Does not come with a support to put the cartridges in. Put mine on outdoor tap for easy access. Works ok, but could be better with longer tubing.
Easy to install. Great tasting water.
Awesome product thanks again
