Query: Worst jumper we tried

Though pink and cute, this thing never seemed to work quite right. The baby wasn't stable in it -- she would flop over forward. Observers wondered if she would fall out. While that never happened, she'd get burn marks on her arms from leaning on its frame & ropes to stabilize herself. Ouch...An annoyance: I had to get help to clamp it into doorways; couldn't attach & detach it myself.It just didn't work for us.By way of comparison: our favorite jumper was the Graco Bumper Jumper. Still working very well for us. She bounces much more often and more happily in the Graco than she did in the Evenflo.
