Purchased 2 Halfords exodus roof mounted cycle carriers in August Used the product twice,and on the second occasion traveling home down the motorway one of the cycle wheel straps failed causing the bike to become insecure and rotating backwards smashing through the rear windscreen of the car. Fortunately there was only my vehicle involved at this time but it could of very easily been a different outcome. I no longer have the carriers as I returned both of them as I believe they are a Dangerous product,Halfords are refusing to pay the cost of the windscreen. After the incident I found one wheel strap to fail locking into position and the teeth slipping out causing a insecure load. I later found out that this product earlier on in the year had been recalled for a very similar defect if not the same but Halfords deny this. So been left with damaged car ,bike and lots of broken glass to clean up along with a hefty windscreen bill!
