Alisa Speller says that after paying Toys R Us an extra $15 dollars to have employees assemble the Radio Flyer Pathfinder Wagon she bought for her 1-year-old daughter Skyla Price, the wheel popped off the first time they used it. Speller says that while pushing Skyla across a street in the Bronx, "I just flipped over it and fell on top of my daughter." While most people would take out their frustration on the poor soul working at the store's customer service desk, Speller is suing the company, saying "If they charge people to assemble it, they should do it correctly." Speller may have trouble proving her case, since the instructions state that adults should "periodically check hardware and tighten if necessary," and note that the toy should never be used, "near motor vehicles, streets, roadways, alleys, swimming pool areas, steps, sloped driveways, inclines, and public highways."
