XHose Pro Extreme – Burst hoses

I purchased three xhoses from Canadian Tire about three years ago. I have a 50', 75' & 100'. They were great hoses while they lasted but unfortunately the 100' & 75' burst recently (one today & one two weeks ago). Im not sure why this occurred but I am not impressed. I dont have the bill of sale anymore for the items bought... I hope you stand behind the products that you sell because not many companies do anymore...
