I've recently bought brand new Ozone Edge V9, 9m, fresh out of the bag deflated after less than 5 minutes. After inspecting the strut bladders I found that two valves of them showed the same problem, namely the valves ripping as shown in the images below.
I contacted to seller. The seller redirected my request to an authorized dealer in Russia. They never responded either me or the seller.
It seems the product’s reputation doesn’t bother them.
Since 2011 I have been buying Ozone Edge’s in sizes of 9 and 11 m2 as soon as a new model appears. This kite gives me a lot of opportunities and pleasure. I don’t want to give it up yet.

PS. Thanks to Ozone and personally to Hannay. The problem was quickly resolved. The company sent a replacement kit
