I'm the guy that Dean is referring to in the first post. I've def had my share of issues w/ the Hydroblade. And I reached out to Xlab for support & replacements, which I received but have not installed, as I was still a bit concerned about the black rubber holding strap. For the most part the setup works.

One of my other dislikes is on a hot day the liquid contends will get very warm/hot in a hurry. Which forced me to try some DIY methods of installation (foil bubble wrap stuff).
