Great in all respects
"I recently replaced my 13 year old APEC under sink filtration system with one with higher output (3/8 in tubing vs 1/4) alkaline water(extra filter to add calcium to water). I am very pleased with it in every respect. The quick connect system makes installation a bit easier and quicker though it was never difficult really. The increased flow rate through the faucet is nice and the water is not only just as pure and sweet as ever it tastes even better. And it is made in USA which is a big plus in my book."
