I have the one from petsmart and we love it,both of my yorkies love to ride in the car,and in the summer my convertable comes out,top goes down,and off we go..I feel it is safe with them attached to the seat belt,and they love the wind in there hair..but of cource we never stay in direct sun..yes,they seem a bit heavy,but neather have acted like it bothered them,I even use it when I take them in the suv,but they prefer topdown days..wish we had topdown days rather than the snow that keeps falling today
