I love this style! I believe it is important to keep the twins side-by-side! I recommend this type of stroller over the type with one behind the other. It's not right to travel and sight see with one twin hidden. Let them both see it all TOGETHER!
I love the stroller. There are however, a few issues that make the stroller a pain at times. The canopy very rarely stays on correctly. I am constantly having to snap it back on to the stroller. The stoller is just a tad bit wide to get through some doorways. Other than those two dislikes I love the stroller. It folds and fits in the back of my car perfectly.
I found the stroller to be difficult to collapse - have to stand on one foot while pushing down on the latch with the other and bending over and pulling up on the two release loops on the back of the seats. Also, if you aren't going completely straight (and someone is holding the door for you) or have the front wheels locked, you won't get through most doorways. My daughter has one where they ride front and back and even though it is long, you can get through doorways without a problem.
However, my grandkids loved riding side by side in it.
