We had one of these of unknown age and it broke when the bike toppled over - to much leverage on the plastic. We liked it enough to replace it, and now we have the "rack" on both Mom and Dad's bikes and one seat. I've used both front-mounted and rear-mounted seats and neither is ideal - it's a little awkward and wobbly one way, versus the other. But biking with the child is still wonderful. This doesn't hold that big a child, our girl is four, petite, about 30 lbs, and her legs are down at the bottom of the "holsters" for her feet. I think this is a good model, the price is good, and it gives you a "rack" you can use with a bungie cord for carrying this or that instead of the child seat. Easy to mount on and off.
