What's important to know about this before buying is that it works. You have everything you need and
more to do some impressive, no-touch peaks.
For me, it's impractical. It requires three
separate components to work, and it feels unnatural to do in an impromptu situation. For non
impromptu situations their are far easier gimmicks to use. Like impression pads and what-not.
It works, it's just not worth the pocket space for me.
