I bought mine from Babies R Us and it's the Caboose Stand-On Tandem Stroller by: JOOVY. I had to buy the parent kit so I had a place for my water, keys and kleenex. It works fine for what I need it for but too bad it didn't come with a parent caddy or this band that I bough that wraps around the handle bars.
It's hard to steer but I have the same issue with the Graco Duoglider double stroller. It's just the weight of having two kids agest 3.5 and 1.5 I think.
I like that it's smaller than the Graco Duoglider. To unfold and fold is not that bad. It is an extra step to lock the wheels but not a big deal. It handles a bit more weight in total than the Duoglider. I took my kids out on our one and only all day with this stroller and my oldest fell asleep sitting upright and it would have been nice to lay her down but not a reason to not buy this.
I'm glad I purchased mine but because of my oldest falling asleep that one time I'll be using the Duoglider for all day outings. If you do many of those and your children get sleepy then I'd advise the Duoglider.
