I picked this up at CT today:
There is a regular version (blue), and the pro version (black). The pro version felt much more sturdy and cost $10.00 more than the regular version. I paid $50.00 for the 50' pro version.
I played around with it today and it's extremely light and manoeuvrable. Try as I might, I could not kink it. In a nutshell, this thing is damn cool, and unlike a typical hose, it's fun to use.
The reviews agree with that, but apparently they're prone to bursting within the first few uses. I say apparently as it's hard to give a failure percentage given that most people who have no issue with a product, won't post it, but when they're pissed, they have much more desire to post their opinion.
My main concern will be its durability if rubbed across a sharp surface. As far as the bursting goes, I'll just return it if that happens.
I'll be testing it on just about a daily basis, as I have a 60' X 120' foot yard with a large garden and a lot of plants.
