Jim, you made me retrieve my Neutron top from a box in the closet. I found that the batteries inside the handle had leaked acid but with new batteries it worked (the lithium batteries on the top itself for the LED lighting still had juice). I played enough to flip the top onto the larger target on the back side of the paddle, but I decided I was going to break it before being able to do any interesting stunts so I stored it again
Here is a video from youtube. In spite of the quality I think it is semi-official.
The second one is a cheap version of the "Maxwell" top. We discussed it on this thread:
