Query: i'm a believer

i was skeptical about these, but i tried them anyway. glad i did.i was worried that they may affect the water pressure somehow, and my worries were unfounded. these things are great. i'm using them for everything.the only problem is that you will realize how many of them you actually need, and you'll buy a lot of them.FYI, i was able to pick up the male+female connector set at lowe's for around $6 (HD doesn't carry this brand). you may want to check there first before ordering here. but as far as the product itself goes, it's top notch.
