Game Changer
Should have bought this years ago. Not cheap, but does an excellent job of both sanding and controlling dust. If you do much drywall work just get it.

Definitely a step up from a manual sander.
It's heavy. It worked great and so convenient with the vacuum attachment. I found that I did not need to order the sandpaper with the holes in it like the manual sander but I used them anyway as I had them in stock . The vacuum attachment needed a piece to make it fit on my shop vac. It arrived pretty fast so that was a plus, as I was not looking forward to the cleanup with the manual sander.

Might be the best tool I've ever bought
Most people would agree - drywall sanding is the worst part of home renovation. Time-consuming and terribly dusty. I took a leap buying this, but it is worth every penny. Better/smoother finish than other methods, probably cuts down on time by 5-10x, and dramatically cuts down on dust. Because it is so effective, I recommend getting a centrifugal separator (~$60; https://www.amazon.com/dp/B0CN7DC7N9?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1) to attach in-line with your shop-vac to avoid caking the filter. That was the weak link. I built a small platform with casters, such that everything moves as one - it is otherwise somewhat cumbersome.

Amazing
This tool made short work of some uneven ceiling repair work I had to do. What would have taken an hours worth of sanding, dusting, feeling out to ensure it’s feathered took all of 5 minutes. Had it hooked up to the shop vac and there was very little dust. Battery usage was not an issue for me since it was not a whole room. I’m As I go thru remodeling the rest of the house I already see the hours this will save me in work and clean up. Light weight and easy to use. Highly recommend for remodelers and for handy men doing repair work where there’s uneven taper in the board from previous botched repair work.

Workhorse with Terrible Dust Collection
If you are sanding skim coats are doing a lot of standard drywall finishing, this tool is well worth the premium. That is assuming that you have at least a couple DeWalt batteries. The battery life is fine. People who complain about the battery life have unreasonable expectations with how much battery life you should be able to get. The machine is powerful to the point to where I almost always run this on Speed 1. What you will need is a lot of sanding discs. That is just the nature of the beast though. This machine would easily be five stars if they would have decided to actually implement some sort of dust collection. They didn't drill any holes for the dust to be sucked in to the inlet in the middle of the power head. If you take off the sanding disc, the sanding pad, and then the little abrasive disc, you'll see that there is no way for the dust to actually be drawn into the machine and then into the vacuum. Not sure what the ding dongs at DeWalt were thinking, but it is very easy to drill a couple holes so that they'll line up with the eight holes on your standard hook and loop disc.

Pure greatness
Works amazing, saves time and pretty much no dust, even on ceilings. One of my best tool purchases ever. Also great for smoothing out old lumpy paint jobs before a fresh coat, wish i had it sooner.

Meilleur achat !
Économie de temps incroyable ! Fonctionne super bien et pas trop lourd. Cest un de mes meilleurs achats! Seul petit "hick" l'adaptateur pour la balayeuse n'est pas inclus

Too powerful?
Works great however the biggest downfall is its too powerful. Seitched to 240 grit pads which helped but a moment too long it starts to strip the paper off the drywall. Ran it on its lowest speed the whole time. It does save a lot of mess. Paired it with the 60v hepa filter dust extractor.

Dewalt never lets me down!
Just another amazing tool to add to my army of 20V MAX Monsters. I operate my contracting company specifically on this platform and have yet to be let down yet. The only corded tool I still have is the dust collector hooked to this sander and it is an unstoppable combo.
