$Irobot(IRBT.US) robot vacuum. I don't dare to make a definitive comment on this field because I've never actually used one. The stock was delisted just before its demise, a final flicker of life. In the end, it's a good thing someone acquired it to provide a safety net and exit, especially since the acquirer has a full manufacturing supply chain and can use this "cousin" as an overseas bridgehead. The acquisition succeeded mainly because it's not that important, right? Even though it was the GOAT back in the day.
