Our testing of the Volo was… not good.We found it excessively complicated and ineffective.
It’s good in theory but it’s a real Rube Goldberg to getting anything effectively accomplished. You have to be a master mechanic, a computer programmer and have time on your hands to optimize it for any particular vehicle. There are just too many variables that all affect each other and the Volo tries to address them all.
While the Volo is a good idea and an excellent technology, I put it in the Chindogu catagory.
I prefer simpler solutions that are user adjustable and address the key issues directly.
