Disclaimer: One thing to keep in mind, is no one that did any of the testing here is a scientist or engineer. So keep in mind there is a margin of error. We`re just a bunch of "regular" guys in a garage sharing our results and data.
This video is in response to Mary B`s request for a sound and vibration comparison between the new FLEX XFE7-15 and the Griot`s Garage BOSS G15. (original thread) Thanks for the request Mary B!
We decided to put the FLEX XFE7-15 against the 21mm polishers because all of the polishers in the test use 6 inch backing plates OEM. Since the FLEX XFE7-15 is powerful enough to spin a 6 inch backing plate, we wanted to test it against other 6 inch polishers.
For sound level data, we used the "Sound Meter" app on my LG G4 phone. After calibrating, we tested the sound decibel meter with other devices and found it was surprisingly consistent. We all agreed it would work to compare sound level between these 3 polishers.
We primed each pad with McKee`s 37 Fast Polish and the same product was used on each machine.
Another request we had was to compare the vibration of each machine. Both Paul and I tested each machine side by side, back to back, and concluded the FLEX XFE7-15 had the least amount of vibration by a very small margin. We tried each machine with thin and thick pads (the FLEX works and feels great with RUPES pads btw). One thing to note is the RUPES Mark II felt like it had the most power, again...by a very small margin. We weren`t able to bog down any of the pads with any of the machines, so the days of stalling backing plates on long throw machines are behind us.
Also, we tested the vibration of the 21mm throw of the RUPES and Griot`s Garage v.s. the 15mm throw of the FLEX. The larger rotational pattern may attribute to the slight increase in vibration, but again; we wanted to compare 6 inch polishers across the board.
Thanks for reading everyone!
If you have any questions or comments, let us know!
i wonder if the 15mm throw w/ 6inch pad has anything to do with less vibration? i wish flex would have went with the conventional route and go 5 inch BP

I`m sure they`re going to offer a 5.5`` bp later on.

Cool video and comparison. What caught my eye was how little the Flex appeared to vibrate Nicks arms/ watch with in use - watch closely as he switches to the GG and then the Rupes - his arms/ watch bounces around significantly more with the later 2.

That`s what I saw with the Rupes bouncing the most. Maybe Nick`s arms were tired.
A society willing to trade liberty for temporary security deserves neither and will lose both

Agreed on the vibration going on his watch/forearms, there was barely if any when the flex was in action. The sessions with each were very short so I personally don`t think there was fatigue.

Ray,thank you so much for that test,Flex is the quietest,the lightest,smallest,low vibrations,i think its my next DA.
Now ill have to wait for the 220v version..
