One of the few genuine brass hose splicers I have found.  Often, they are actually made of (cheaper) aluminum, with a brass-colored coating of some sort.  The barbs are cut cleanly and burr-free, and there is a shoulder in the center, so that it goes into each hose at an equal depth.  To top it off, the included hose clamps are well made, and appear to be all stainless steel, instead of a stainless band, with a coated worm screw, which will rust over time.
