Could be a good product and I can see the advantages, but this quote by the "product developer" made me chuckle:
"Like other RVers out there, hooking up my weight distribution system made me anxious,” said Product Developer Dave Gramlin. “I was tired of dealing with noisy, cumbersome and potentially dangerous chain systems that sometimes left me with bruises.
Bruises??
In 9 years of using the chain system, I was never anxious and never got a bruise. Simple to do if you know how. Some apparently don't.
From a marketing perspective, this looks like a very good idea if you can convert thousands of the old chain systems.
