I used fab stone countertops and one of the go to polishers was Flex. Metabo was another.
I bought a Flex years after I got out of that trade. Unfortunately, it was junk.
It failed within a few hours of use. The rep I called at was super responsive and sent out a new unit with no questions asked.
It failed within a hour. Turned out to be a switch. Not sure what the first failure was. Likely the same thing.
I’ve owned allot of Porter Cable tools over the years with limited positive experience.
That said, I’ve not had a P.C. polisher.
I’ve used em and they work fine. I’m just not sure how they hold up to hard use over time.
Given my extensive experience with the brand, I’m not optimistic
In the 30+ years I’ve been in the trades there’s never been one brand that has all the best hand held power tools.
At least until recently. Milwaukee seems to have monopolized the market. Dewalt is certainly a player as well. I still have several of there tools. Personally I’m not a huge fan.
But, some are very well designed and have been in use for years.
P. C. Not so much.
Most tradespeople I know myself included, now use Milwaukee almost exclusively.
I think, largely due to to the fact that almost all hand held power tools are now battery op.
We don’t have the luxury to mix and match like we used to.
Milwaukee has been very aggressive with both marketing and design. And, they make good tools.
One of the few 18V Milwaukee tools I don’t have is a orbital sander. It’s on the short list.
Another contractor friend has one and loves it. Not sure if they make polishers ? Probably.
I own more HF tools than I’m comfortable admitting to. They’ve done there job and then some.
I’d never consider buying a polisher there though.
Spend my lousy $ .2 as you see fit. Let us know what works.
