Some clarification on this new balancer please?

Anytime.
Most of us expect a parts wholesaler to have the details/info of the product brand they carry, right? Summit has many, just like Jegs, that have about no helpful info.
I sure as heck don't expect it. I never buy a part from them that I don't know 100%b already. Distributors for auto parts are like distributors for anything elss.... they are good for 3 things:
Pricing, warehousing, and shipping.

Never expect technical expertise from them. I follow this rule in dealing with distributors in my regular business and don't get caught flat-footed.
