Has any one got an X box trolley ?Do you get on with it? I have just bought one and am not very happy with it. I will be taking it back for a refund as I think it is designed for the old on box model with the V down the center of the seat which the clamp sits in.My old boss trolley seems to fit much better with full support under neath the box .I thought the manufacturers trolley would be much better but i'm beginning to think i was wrong
