Couldn't agree more.
Trading standards all the way, that is depending upon how I'd paid to begin with.

This item is not fit for purpose, In my opinion totally regardless of some members saying that it would put the industry out of business blah blah.
You've used the item as provided, stock out of the box, at speeds it's capable of, at heights it's capable of jumping (without descending from ground higher than which it started) such as cliff edges, all self propelled.
Plain and simple, unfit for purpose.
