I purchased this polisher because it was 7in. rather than 6in.PLEASE keep in mind this is a POLISHER not a buffer this tool is intended to apply and remove polishes, not to remove swirls and defects.However dried caked on wax will be hard to remove with any polisher !! best on paint sealers and polish. I use mine daily and love it !!! VERY easy to hold.
Sorry to report that this buffer/polisher was not up to the task. I bought it to polish my fiberglass boat, but if any pressure was applied greater than the weight of the polisher, it stopped rotating and vibrated only. Using its own weight was not adequate to remove the polish.
I bought this two weeks ago, and I am very satisfied.
Its unacceptable that Sears sent me an used item.. Box damaged, missing accessories.
This thing don't have enough power to do anything. Will be returning.
