Hi, I’ve got a SPRK+ which I noticed was rattling. It turns out one of the blue bits has somehow snapped in two. I’m not sure if it’s the wheel or gyroscope or something else (I think it’s actually the idler wheel assembly, whatever that is…). Don’t really want to buy another because of this, I expected it to be more robust… not even sure how it could have happened, it hasn’t been dropped from a great height or anything. And are these fixable? Thanks!
