I bought the rumble seat and buggy board for the older UB Vista from someone on Craigslist, back in July when I got nervous that UB would stop making the old versions. Just had the baby two weeks ago and finally tried out the seat and buggy board. The seat is great, but the buggy board is missing the pieces that attach it to the stroller itself. I'm pretty annoyed since I paid more for the two pieces combined than the rumble seat alone retails for, and basically all I have is the rumble seat now.
I emailed the guy I bought them from but I doubt he still has the extra parts- I'm guessing they were attached to the stroller still and he sold that separately. And I doubt he will offer me my money back. I'll call UB on Monday to see if I can buy just that piece but I have a feeling I'm just out of luck. Sucks. Any other ideas?
