UnstableImage.com is a great photo blog by some really enthusiastic photographers.  In this review they take the strap from unboxing to full out review over two parts (posted a week apart).

“So I pulled the trigger on one of these bad boys last weekend. I was over near my ‘local’ photography supplies store and thought I would pop in and have a feel/play with one of these straps. I discussed at length with the salesman about his experiences with the strap, then tried it out for myself.”
