I have experience with the Aria double! I had to return mine 3 times...the 3rd time was the final time. At that moment, I opted to buy the Maclaren Quest single. (My son is 4, so he is RARELY in the stroller anyway and didn't want to spend that much $$ on a double since I will rarely use it.) I had many things happen to the Aria double while I owned it:
1 - The canopy's ripped on all three of them. Not rip like a HOLE, but ripped so that the fabric was frayed on the ends. It looked like a run in a stocking and went ALL across the canopy.
2 - The ARIA and PEG PEREGGO stickers come off VERY easily.
3 - On two of the strollers, one of the front trays locks broke and the trays couldn't stay down
4 - One one of the strollers, the wheel stuck
5 - The basket underneath is HUGE! I loved that about the stroller. However, the cardboard in the lining bends and causes the basket to drag on the floor. It is attached to the stroller by little BUTTONS. I had the basket come undone on all three strollers MANY MANY MANY times. VERY ANNOYING!!!!!!
6 - The double, IMO, was hard to steer with a 40 pound kid in it! It is supposed to hold up to 45 pounds in each side, but I found it a chore to push it while my son was in it
Other than those issues, I LOVED how light it was and how compact it folded. But since it is an expensive stroller ($330), I didn't see wasting that kind of money on a double that had so many things wrong with it, and because I wouldn't use it much to justify that cost.
(For $330, the strollers shouldn't have had this many problems!!!
