In reply to yorkshireman:
I've tried these via Ebay and so far, out of 4 bought 2 are leaking with a handful of uses and 2 are untried.
Of course, in the world of fakes and look a-likes I may have fake ones and these could be great... who can tell? I was struggling to justify near on £18 each on genuine Salomon ones and didn't fancy what were probably fake Saolon on ebay from far east so thought I'd try cheap ones that were at least honest about not being Salomon to see what happened. Waste of time so far. But I still struggle with £18 for Salomon ones. Fair enough my originals lasted well but they still burst eventually despite careful use and they are just plasticy bottles for heavens sake! I think my race vest with 2 bottles cost £100 and around 40% of that cast in the bottles seemed crazy!
I just wish I could find a mid priced, non brand name equivalent that doesn't leak... or at least lasts a similar time to my originals. I didn't want super cheap Chinese ebay imports but equally I didn't fancy £36 on a new pair of genuine.
No idea what to do to replace mine now.....
