Sure. It's cold, rainy, and midnight but here's what came up in my email when searching "vacuum". It's not all, and you can see some I didn't reply to but -
That said, thanks for sharing the emails/headers.
It's curious that Amazon hasn't flagged you for purchasing & reviewing multiple similar items in such a short span of time. I would imagine it would be quite easy to spot someone who's bought and reviewed 12 vacuum cleaners in a 2 or 3 year window.
