...you make some good points and I wonder about the thing, too. As someone else said, it looks a tad delicate, and to be frank, I dont think I could swing that coil for long without laughing.
He/she should indeed solicict for testers and may have already done so, as far as we know. He DOES indeed need some testimonials from those in the know, whomsoever those "people" may be. That would add credence to his/her eforts
However, if the thing actually exists (it does look in the pics as if it could be a "graphic simulation"), I admire the brass of the maker, whoever it may be. Marketing a new product is no offhanded affair as you may be suggesting. If you've ever been involved with a new start up business, you know what I mean. Sometimes it's only possible, due mostly to budget constraints, to do it from "out of the trunk", as this maker seems to be doing.
I suppose we should wait and see - and offer to help test it, if you can tolerate looking at it, that is! Uggghhh. No offense, but it tis ugly!
