From Ozone Kites:
This is a safety notice for customers of our 2011 Inflatable Kites to check the serial number found on the leading edge as shown in the following PDF: Ozone Kitesurf Safety Notice – Bladder Valve Detaching
It has come to our attention that there is a manufacturing defect on an early batch of Ozone 2011 water-kite leading edge bladders. There have been cases of the valves detaching from the bladder causing instant deflation of the kite.
As a precaution we will be replacing all customers with a new leading edge bladder for all kites with affected serial numbers.
Please go to the website (see below), input your serial number and automatically check if your kite is affected: http://www.flyozone.com/kitesurf/en/products/bladder-safety-notice/
If your serial number is affected, please contact the dealer you purchased your 2011 Ozone inflatable kite(s) from to organise your replacement bladder(s).

Ozone is committed to safety hence our decision to announce this safety notice due to a small percentage of defective valves. Ozone wants all customers to be able to enjoy our products and would therefore like to apologise for any inconvenience.
