We faced a dilemma for 23 mth toddler twins. Our twins are walking but still getting used to long distances. Pushchairs are still needed. We dont drive & used tubes & rail when we were single. New problems. Can't use our Icandy pear at tube & rail stations with no lifts as its too heavy when both twins are in to lift down steep stairs & can't leave 1 twin at top & carry 1down & the puschair & believe me no-one rushes to assist you with a dbl pushchair.
Our solutions were taxis : but its too expensive as our family live out of town.
Harnesses: never thought I'd use but they ll run in 2 different directions otherwise. But they get tired of walking after short distances & carrying over 30 kilos of twins isn't easy.
Baby carrier: Bebo still comfortable but only for 1
Pushchairs: Icandy too heavy for stairs & end & middle stations aren't step free. Umbrella double is too wide for tubes & same problem with steep steps.
Bus: not practical for some long journeys
So quicksmart backpack vs quinny yezz considered ie foldable backpack pushchairs
Bought both to compare. Quinny looks very cool & folds in & out in seconds. This is essential as if 1 twins runs off, I can still grab the other twin , fold down the quinny & sling it over my shoulder or put twin2 in it & run after the other. Also if I travel on my own I can put 1 in the bebo carrier & just carry or put the other twin in the quinny.
The quicksmart takes alot longer to put together & the backpack one has to be put in its backpack to carry. It is however a lot cheaper new or 2ndhand than the quinny yezz. & shamefully I'd say, doesn't have the swagger of the yezz. Many compliments from mums on our yezz & easy opening.
Re tipping issues. I'd read quinny has a tipping issue which is why I bought 1 of each. You can't put heavy shopping bags on the yezz, there's no place for them above or below, deliberately I think as they do make it tip, with or without a baby. I wouldn't leave a baby unsupervised in it because Houdini babies (got one) , easily get out , so they may tip it when moving up & out. It's just for moving them A to B quickly.
Yezz can be moved with 1 hand whereas quicksmart needs to, which is handy for airports with carry on luggage.
You can't put a cars seats on either but after a year our maxi cosis stopped fitting on their pushchairs anyway . Hopefully when theyre older & heavier we can carry portable booster seats.
The twins fight to get on the yezz as they love how it rides. It's like a stripped down sportscar in terms of features. We are getting a 2nd yezz for my OH. He prefers the yezz. (Think on looks more, :-)). Ours isn't new but looks it. I think we'd get a year out of either of them now as the pushchair is low & our twins are getting tall. Bit pricey but also available 2nd hand. I can see why people using American metro /tube go crazy over this.
Hope my review assists.
