First, the braking system on the Vibe is much easier to access than the other P&T models. TOO EASY. In fact, all you have to do is lightly run a finger over the red brake button on the center of the handle bar and the whole stroller halts to a stop. Incredibly dangerous on a downhill trip!!! The twins have been jerked forward way too many times for me to count. I may be clumsy, but they just make it way too easy for me to hit that brake by accident.
I tried to return the stroller to the store today. First, they couldn't decide whether I could return it or not. Granted, the stroller was purchased in October, but I haven't used it until a couple of weeks ago. They have a satisfaction guarantee--and I'm NOT satisfied. They then tried talking to the P&T distributor, Regal Lager, to get a return authorization. That was denied. The distributor maintains that the breaking system is not a hazard and would not take responsibility for it. Finally, the store manager returned the stroller for store credit. It's a good thing I buy formula and diapers every two weeks. The GIANT store credit can come in handy. They even matched the prices I was getting on Diapers.com. Not a bad save on their part.
As a replacement, I bought the Mountain Buggy Urban Elite--from ANOTHER store. It is a side-by-side stroller--with four 12" wheels-- that can still easily fit through standard doorways. I wish I had researched this stroller earlier, because they offer carry cots/bassinetts to fit onto the stroller frame for the younger babies. For twins, you can either buy two separate cots or one larger twin cot. For a baby and a toddler, you buy just one cot and leave the other seat alone. Since this New Zealand brand just filed for bankruptcy in January, there are great deals to be had. I bought the top of the line model for 40% off retail price. My hope is that someone buys the brand and continues to make accessories and parts for it. We'll see!
