That hose may "kink", but I believe it is one of those hoses that still flow to an extent, even when kinked. They have ribs that run the length of the hose on the inside that keep a space open in the kink. OTOH, if you cut it and try to use a hose mender, you'll find that those ribs ensure it will leak when clamped onto a barb.
Have there been developments in garden hoses. Yeah, but nothing great.
Those expanding hoses look AWESOME. I suppose they might make sense if you can justify buying a new one every year. I've had my Craftsman and Goodyear hoses for about 10 years now with no troubles.
The Goodyear hose "lifetime" warranty still isn't worth the paper it is printed on (just look at the fine print). The Craftsman hose lifetime warranty is still rock solid (as much as people here will bash Craftsman).
On one side of my house I have two wall mounted hose reels. One has two 50' black rubber hoses on it for everyday use. The other has a 150' extra cheap green hose for the walking sprinkler. The rubber is both heavier and stickier, and the walking sprinkler struggles with it if it is pulling more than 50' or so.
The other side has two 50' rubber hoses in it. The inner one (the one that sees less wear) is a Goodyear red hot water rated hose. I've used it for flushing my boiler, etc. Seems ok enough.
