Review: Absolutely top notch. I have used all the versions 1, 2, 3 and 4 and this is version is extremely well made. Be mindful of the full length of the mated fitting - it's long. Zero drips and very easy to attach the tubing with the long barb and compression screw. A+ design and heavy weight, durable materials.
