Well, I really wanted to like this. The idea itself is pretty nice, but there are a few problems with this:
First, the tutorial really feels like someone was just trying to rush this to market. It's in a crowded area, the person is not well heard, and the whole thing feels and looks like it's a rushed explanation to someone in a magic convention and not a thought-out explanation that you can see somewhere else in other products.
Second, the performance is not in front of "Real world people". Well, there is none except the one on the page here. I say this for the reason that one of the moves is covered by something you wouldn't do to someone who isn't a magician (Don't want to give away the method so trying to be subtle with my words here).

So the idea is really nice, but the execution lacks. Sorry to say this is really rushed to market and could use more thinking.
(this might say I'm not a verified buyer since for some reason this doesn't appear in my penguin page, but I have the recpit and bought it from here...)

This is a fun and clever idea. The fact that these flossing tools are so common really helps disguise the method and sell the illusion. People have a preconceived idea about how these things should be constructed and I'll admit that I had no idea how this trick could work before getting the gimmicks.

The teaching is a bit unconventional; The creator is demonstrating the method to someone at a convention (the same setting seen in the demo video). I didn't mind this because, really, the gimmick does all the work. What you see him doing in the demo is pretty much what you do. He does discuss some covering moves and handling suggestions but the method is pretty straightforward.

The gimmicks are treated with some sort of material which give them different properties than normal flossers. They pass muster when handed out briefly but, like the real thing, are small and delicate. This leads to my only real concern. I've had people treat them pretty roughly when trying to replicate the linking and, when it happened, I cringed inside. My suggestion: Allow the spec to handle them exactly as shown in the demo and no more.

If there are durability issues, I'll update this review. Until then, I'm very happy with this cool little EDC.
