Interesting. Similar concept but clearly different design. I love how they supply a push pin And doesn't look like they use a jig like the IG Wrap does.
I don't see much difference in the design. Pretty much a copy, including the size, groove, corner wedge and staples holding the corners.
For those doing only a few, the fact you buy a single kit for each stretch is probably a nice thing, since with the others you have to buy several bars of each size, resulting in enough to do 4 stretches is a minimum. If doing a lot, the ability to mix and match sizes is nice for the IGWrap bars. These appear to be a little cheaper, although BC and Liberty discount these aggressively most of the time.
Personally I like the jig. seems to make the placement of the bars to achieve the correct stretch much more accurate. When placing the bars freeform like this I can see problems because you misplace one by a fraction.
Several of the tips in the video might be helpful for those using any of these systems (such as the push pin to locate corners).
