They`re coming in very competitive at that price point at $240/$250, which is much less expensive than the previous gen when first released. Bit surprised they`re dropping the BOSS nomenclature I was not expecting that, but I do like this body design a lot. Trigger on these will be a progressive variable speed trigger which differs from the on/off trigger of the G9. New cooling integration on the backing plate, and this feature has me very interested as well:
"Balancing the combined weight of a backing plate, buffing pad, and the liquid on the pad translates into less vibration and a smoother running machine. For instance, microfiber pads generally weigh nearly twice as much as a foam pad so fine tuning is beneficial. Our innovative Weight Optimization System consists of three uniquely engineered fasteners, each weight-matched to a Griot`s Garage pad type to ensure you`ll enjoy best in class performance from these machines."
And the below pulled from the online manual: https://vidweb.aws.marketlive.com/gr...0915_10921.pdf
G15/G21 WEIGHT OPTIMIZATION SYSTEM
There is a proverbial dance that occurs between an orbital polisher`s counterbalance and the combined weight of a backing plate, buffing pad, and the liquid on the pad. Balancing this combined weight translates into less vibration and a smoother running machine. For instance, microfiber pads generally weigh nearly twice as much as a foam pad so fine tuning is beneficial. Our innovative Weight Optimization System consists of three uniquely engineered bolts, each weight-matched to a Griot’s Garage pad type to ensure you’ll enjoy best in class performance from these machines.
So a way to fine-tune the balancing of the pad on the spot which is going to work great for working with a variety of different pad types. Very cool stuff coming out at Griot`s this year, can`t wait to hear some feedback from the testers.
