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.

A game changer!
This is one of the most game changing tools I have purchased. I am an interior home remodeler, so I do many other things aside from drywall and can say this is worth every penny. I was hesitant for a long time before purchasing this, and now regret not pulling the trigger earlier. It cuts down on sanding time at least 5x and leaves the wall with a near perfect finish (very light manual touch ups may be necessary). Pair this up with a 5gal Rigid vacuum with a HEPA setup and the floors are COMPLETELY clean afterwards. Easily achieves 99% dust extraction. I do not regret this purchase.

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.

Worth every penny
Absolutely excellent. I’ve used porter cable power sanders for over 20 years and I’m really impressed with the Dewalt. I bought two 6Ah batteries and one battery sanded about 90 10ftrs (3600sq ft and there were an alarming amount of Butt joints- probably 30 too many- which is more sanding obviously). The sander is very quiet and does not have a power rattle-it turns on smooth and turns off smooth. The telescoping neck sold itself- it makes you wonder what took so long to see that on a sander-closets are now a breeze. The price to me personally was amazing to have one less cord in your set up. You’re also saving money because you no longer Need a tool activated vacuum- you can go buy a 5 hp rigid vacuum which the hepa filters and bags are cheap. For how much We use the power sander(at least twice a week) they usually need to be replaced/rebuilt every two years- so this power sander being about 400$ is great- and the batteries (sold separately) have a 3 year warranty. All in all a great sander- it is a little heavier than the porter cable but you get used to it very quick- and not having the power cord is one less thing to annoy you!

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.

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.

Works as should
It does speed things up goes threw batteries a bit slower than I expected. One complaint is it would b nice if it could extend one more foot for 9ft ceiling it does reach at its current lenght but a little more to work with would b nice get ready to lightly sand everything out when. Your doin your light check will leave swirls all over the place whem getting used to it than you'll leave half as many once get the hamg of it. all around a good tool that does the job as expected
