I'm not a fan of these shorter stroke gear driven polishers. While they vibrate less than a Flex 3401, they will jerk you around worse.
I'm vindicated. NOTE: I made the letter "S" in the word polishers in Mark's above sentence BOLD. I don't want anyone to think I'm picking on a brand, I'm just talking about my experience with a "type" of tool and the type is the two brands of 5mm gear-driven orbitals on the market because I've experienced this characteristic with both brands.
I've posted this numerous times on this forum and not to downplay the Mille or the Makita PO5000C, which we no longer sell due to low demand, (same orbit stroke length so same action), but to let people know one of the
characteristics of this style of tool.
On a flat surface, all tools are smooth, (in context of "tools"), but when using a 5mm gear-driven orbital and moving the face of the pad held flat to the surface of a given plane, to a curved panel, (transisitionin the face of the pad from one plane to a new and different angled plane, the tool will exhibit a jerking or hopping reaction. This happens with the FLEX 3401 too by the way it's just not as noticeable once you're experienced with the BEAST.
Just to discuss, let me start with documenting some history.
I posted my review for the Mille on
12-22-2017, 12:16 PM, which is shorty after it was introduced at the normal place most new tools are introduced and that's SEMA, which always takes place the FIRST week of November. So generally speaking, I posted my review 5 weeks after the tool was introduced in 2017.
To this date, I'm pretty sure it's the most picture-intensive review to date. Maybe someone can find a more documented picture and text review somewhere else?
Review: RUPES BIGFOOT MILLE LK 900E by Mike Phillips
The RUPES BIGFOOT MILLE LK 900E Gear-Driven Orbital Polisher
Fast-forward 5 months and I held a free detailing class and is my norm, I let everyone use whatever they want to use.

700 HP Hennessy Vette and Jeep Cherokee - Waxed and Coated
Here's my friend and 3-day class alumni Edson, testing out the RUPES Mille on this old 2-door Chevy. He's using the 125mm backing plate with the 140mm pads, for us non-metric folks, that's a 5" backing plate with a 5.5" pad. He comments to me about the tool pulling him around as he's buffing on the front of the Vette.
So I stepped in to see what was taking place. I've taken the 3rd picture above and drawn some lines to help explain the area and the PLANES.
Planes = a defined section of paint where the surface is of the same level.
I'm buffed the section in the below picture. This section has 2 PLANES.
In this picture if drawn boxes around the two different PLANES.
When buffing in the driver's side middle of the front clip and moving the buffing pad over to the secondary plane, where the hood transitions to the panel around the headlight and the top portions of the fender, the pad will tend to pull or jerk the tool around as the face of the pad transitions from one PLANE to the other PLANE.
The above about as best as I can explain it with pictures and a keyboard.
And here's the important part - I'm not saying this is a negative thing, it's just a CHARACTERISTIC of a very short oribit stroke length gear-drive tool, no matter what the brand.
I'm so glad I have a history of saying and typing the same thing for the BEAST, that is when others on purpose or simply due to a lack of taking the time to properly express their thoughts via the written word talk negatively about how the FLEX 3401 aka the BEAST has a "WALKING EFFECT" - I've never typed about this as a negative aspect of the tool, simply a CHARACTERISTIC of a 8mm gear-driven tool.
The BIG PICTURE is this, if you spend enough time with any of these tools you become accustomed to their CHARACTERISTICS and adjust to them. You GAIN pure brute POWER and lose the pad stalling CHARACTERISTIC of free spinning tools.
Make sense?
No free lunch in this world - in other words, getting the zero pad stalling aspect or feature of a gear-driven tool, no matter the brand or the size of orbit stroke comes with a price and the price is it's obviously less smooth as a free spinning tool.
By the way, I'll be covering this topic in one of my classes at Mobile Tech Expo in a few weeks.
I have 8 classes at MTE This year, here's two of them...
9:00am to 9:50am
2: Short Stroke vs Long Stroke Orbital Polishers – Differences & Benefits
Some people say long stroke is the best. Some people say short stroke is the best. The reality is, there’s a time, place and best application for both long and short stroke polishers. In this class you learn the differences in both types and the benefits for both types plus finally figure out which type is best for you. If you’re just starting out – choosing the wrong tool wastes not only time, but money in the added costs of pads and products. Generally speaking, while there is something to be said that the more you spend the faster you can detail, there is also something to be said for a low cost tool that can get the job done and get the job done just as well and just as fast. Come to this class to find out.
10:00am to 10:50am
3: Free Spinning Orbital Polishers vs Gear-Driven Orbital Polishers – Differences & Benefits
In this class you will learn the MOST IMPORTANT DIFFERENCE between ANY free spinning polisher versus ANY gear-driven polisher. The difference equals time and time equals money. You will also learn which tool is better for finishing softer, finicky paints and which tool is best suited for doing the grunt work. PLUS, learn the 2 types of HUMAN ENERGY required to use a free spinning orbital polish while the gear driven only requires 1 type of HUMAN ENERGY. This difference is never considered or shared anywhere in the detailing world and it makes a HUGE difference on YOU as well as the overall time you invest into any paint correction work.
