Having just seen someone selling these for £17 i felt compelled to say they are FREE from Dorel (The Quinny parent company)
Quinny have realised that the straps on the Quinny Buzz are a little too short so have produced extensions, to get a set all you need to do is call
and ask for some Buzz Extension straps, they will send you a set, completely free of charge, no questions asked
I hope this helps someone save a fortune!!!!!
