Bests & Worsts Reviews from Amazon

A Christmas present for my son. It was the one big thing he wanted. A total hit for 20 minutes, but after maybe a half dozen jumps, the Sumo stopped jumping. Did a little online research and quickly saw that others were having the same problem. Following a tutorial on YouTube, examined the internal jumping mechanism and discovered that the wheel that retracts the springs on the jumping foot had broken. It's made of cheap plastic and snapped where the jumping mechanism grabs it to pull in the jumping foot. From a look at the reviews here at Amazon, it looks like this is a very common problem, especially with recently purchased Jumping Sumos. This is either a terrible design or there was a significant quality control problem at the factory that makes these parts. Still, my son really wanted this to work out, so I called Parrot support. What a waste of time! They were totally unhelpful and actually got a little snippy with me when I suggested this was a widespread problem. They said they didn't know what was causing it, and they told me to send my unit back to their warranty department (which they outsource) for a replacement which would take 4-6 weeks. I said that was unacceptable, but I'd be willing to keep the Jumping Sumo and fix it myself if they sent me a supply of the plastic jump wheels. They said they couldn't do that. All they can do is a full unit replacement which will take 4-6 weeks. I asked if they wanted to see the pictures I took of the broken jump wheel (see below). They said no. At this point, I gave up. The Jumping Sumo is going back to Amazon for a refund. Maybe we'll try again after Parrot acknowledges the issue with their factory or makes a design change.
