Jiggernaut was something I held off buying for a long time, I looked at it many times and always though it looked "gimmicky" and didn't get around to buying it. I am not too proud to say I was wrong! In fact 2 days after buying it I bought one for a friend I like it that much...
For those of you who like to work light and perhaps doa lot of close up / strolling / table hopping this is (in my opinion at least) the perfect solution as it weighs next to nothing but allows you to do a full cups and balls / chop cup type routine which instantly resets.
One of my favourite chop cups in the world is the RNT2 Heavy Copper Strolling Chop Cup however, as much as I adore this cup I couldn't imagine having it in my jacket pocket all night without a truss. By the way, I use my RNT2 a lot and I would higlhy recommend it to anyone, it's just a little heavy for stolling in my opinion. Of course there is always the aluminium version folks

Jiggernaut has solved the weight problem for me nicely and it uses natural objects everyone is more than familiar with.
There's a couple of photos and some more info here:
