my bad, delete this.
No reason to delete it. I'm glad you posted about it.
I exchanged a number of emails with the guy years ago when he sent me one to try. I tried to contact him some time back, but never got a reply.
I just now tried to contact him through his website contact page. Always thought it would be cool to invent some kind of tool and try to sell it.
I have a special clamp I made for clamping off them larger pump hoses on the front load washers.
I should post a photo of it some day.
