Last night, by chance, I was browsing eBay and found myself a G1 Soundwave with Rumble (AKA Frenzy or Red Rumble). The bid at the time was 10 bucks, and it was 12 minutes from ending. At 6 minutes from end, I put in a bid for 10.50. At 5 minutes, someone else put in 11, I put in 12, and then 2 minutes, I raised my maximum bid to 15.
Got it. This is my bounty:


Was it worth the 15 bucks? I'm using it primarily as a display piece, rather than a collection piece, so it's fine without the box, but is there a piece missing? I can only assume that the batteries are in the back part, but is the back part gone as well?
It should be arriving in 2 weeks. I'm excited.
