My Wintecs hose is about 13 years old. If i reel it right out i can see their phone number printed on the side of it. Not sure what the quality is like now 
We still have some minibore on one of our now standby hose reels. We purchased 2 of them from Cleantec in Scotland before they folded. That was back in 2006. Tough as old boots but very stiff, even when the water was warmer in summer. But what a difference using that to the 1/2" garden hose Peter Fogwill supplied with his trailer system back then.
That hose will last a long time in everyday use. However, most window cleaners, like myself, now prefer more flexible hose as it's easier to manage. In my experience, the cost is that the more flexible hose isn't as durable.
