Not same as the Solar device. Just a little oval shaped piece of plastic containing a magnet on the back that would "attach" to the bullet button. On one part of his packaging, he says the word "tool" but because it attaches itself to the BB, I think that's a hard sell.
A couple ways to look at this is the guy that's selling it is trying to dupe people (noobs) into thinking he's selling a little piece of plastic, that won't put them in jail. The other way to think of it is that the guy is also selling it to people who know the law and will casually palm the device if the gun is to be inspected (nudge, nudge; wink, wink).
Either way, he's scum ...
