Product review (4 stars): So far, so good.
UPDATE: After 2 1/2 years, these are still working.

I have been a fan of the stainless external braid hoses for various plumbing hookups, but the price/length value that this set represented was compelling.

There's a lot of FUD about the stainless external braid being "just a simple hose inside a braided shell", but the fact is that the braid provides both abrasion protection and mechanical support for the internal tubing, and I have sections of it that have been in service under pressure for over 20 years without a failure -- and on hot water. I have never had any stainless-braided hose fail in service. I can't say the same for rigid PVC or CPVC plumbing, or even copper pipe.

I have no reason to expect this set to be superior to the braided stainless variety, and it certainly doesn't look as good.

But this set is definitely less expensive than a comparable length stainless-braided set, and I like the right-angle connectors on one end. The build quality appears excellent, and both ends were drip-free with moderate hand-tightening, indicating good mechanical tolerances and quality washers.

The one missing feature is a marker to distinguish the hot and cold lines. I marked the metal portions of one hose with red paint to indicate the hot circuit, but there really should have been a colored plastic sleeve or clip or tag or _something_.  The lack of this feature (which is present in other washer hookup sets on Amazon) cost this set a star.
