Customers say

Customers like the quality, value, ease of use, weight and speed of the polishing buffing tool. For example, they mention it works as expected, it's easy to control the wool pad and that it has adjustable rpm. That said, they appreciate the variable speed trigger and that the unit is heavy for heavy work.

I beat this thing up for a living

I beat this thing up for a living
Thickness? Why is thickness a rating on Amazon? I guess it's a "medium thickness". I dunno. Ok, I'm a professional boat detailer and I use this machine almost everyday. Sometimes for 8 hours plus of constant use. I mean if there is anyone dewalt should be worried about as being a tester, it's me. I use dewalt because out of all the buffing machines and all the different brands I like the smoothness and the torque these machines provide. Others are just different. These are almost instant and when you feather the trigger they seem accurate and predictable in conjunction with how much you depress the trigger. I use the heaviest gauge cord possible to hook these up because it will make the armature last longer. It has to do with the flow of electricity and smaller cords have this machine run hotter than normal there by wearing out the internal parts faster. I clean out the vents and change the carbon brushes about every 3 months. Do these things and this will last well over a year. I really really abuse this thing. Also something to consider is the Square Trade warranty. I recently used it and I wasn't too impressed. Ya they answer the phone, you get a person who you can understand and all but they don't fix them, they replace them. BUT, they replace them by cutting you a one time check and I paid almost $200 for the buffer (not including the $20 Square Trade warranty) it and the check was for $139. It's better than nothing. Maybe I can send it into Dewalt or bring it to an authorized repair shop and have it fixed for less than $139. Also something to note is I buy these off of Ebay also, but because I did, Dewalt would not back up there warranty on the machine and said "we don't honor the warranty because you bought it off eBay". This is why I bought it off of Amazon, I'm gonna try to go through them when this breaks and if it doesn't work out with Amazon, hopefully Dewalt warrants these machines if bought off of Amazon. I'll post an update when I give it a try. Square Trade was a let down.
