We love this stroller! We just had twin boys and we have a two year old and we are able to fit all three children in the stroller at the same time! Fantastic. It is super easy to push and very smooth. Although it is on the heavier side of double strollers (maybe a pound or two heavier than some of the other top brands) it pushes like a dream. There are several different ways it can be configured and it can have a different type of seat on each side... one side a car seat the other a carry-cot, or a car seat and a toddler seat, or two car seats Etc. There are a ton of accessories that can be used with it (though most have to be bought separately). It is extremely versatile and will grow with our children from infancy until they are out of strollers all together. For a side by side double stroller there have been very few times that we have run into a problem getting around in stores, malls etc. We have the red stroller and it gets more attention and comments than our twin boys do! We have been stopped on several occasions by new parents or parents to be asking where they can get this brand.
A few cons... changing the configuration from one seat type to another (car seat to carry-cot) does take some time and some parts have to be removed and others added, so you have to know ahead of time how you plan on using the stroller. We have found though that we don't really switch it around too much so it's not that big of deal. While there are a ton of accessories, they have to be bought separately which can really jack up the price of the stroller. We bought ours online at http://www.momandbabyworks.com/ for half price so we were able to get the accessories that we wanted. The only other downfall is it takes up a lot of space, but so does every other double stroller of this kind.
Overall I would highly recommend this stroller to anyone and I would certainly recommend any stroller from Easywalker based on my experience with the quality and dependability of the stroller we purchased.
