I used to own this stroller (before it got run over!). It's sturdy and dependable, not like the cheap ones the pet stores sell- that when you push it, it feels that it will fall apart. The double wheels are what make it a smooth ride. The cup holder and little cubby up top is great to hold your keys, cell phone and pet treats and the cubby at the bottom can hold shopping bags or your purse! We also put a blanket down there. Its really good quality and I am thinking of purchasing a new one!!
