I was interested in a cobra as well. I wanted to do some research on them first. I don't think you can wash those...not sure? If so, then I know that's not for me. I want a washable hose.
In regards to the Nammor, I have one. The damn thing fell apart on me within the 5th use. And I didn't even use it often. I used it once every month...twice at most. They are amazing hoses. I love the pull, the look, you can wash them..they are great in that aspect. I just don't like how a $20 hose can fall apart so fast.
Like I said I'm in the market for getting a new hose as well. So this thread is helping me out too!
