Well these things are unbelievable first of all ..if you never used one you will be in for a surprise .. great at leveling and such a fast and smooth finish ..I wish I had used one years ago ..of course at my age now ( 68 ) what a lifesaver ..makes sanding so so very easy and nice ..not much dust at all ..not really heavy ( the ) brush-less one is much lighter but it has to a have vacuum to use ( this one ) doesn't and I just am blown away at how the vacuum works ..not much dust at all compared to hand sanding .. the way the dust collects in the bag and ease to dump it ..would never have believed there was that much dust but this thing collects it that easy instead of it going all over the place!
Really ..I told two of my brothers about them ..I said if I had to ..I'd buy them for them .. it's such a great product ! They did buy the same as me ..the ceiling one and the hand held one ..the price and product is so very worth the $$ ..can't wait to hear everyone else's remarks ..I know I'm so looking forward to sanding now where I hated it before ..nothing to it..what a time saver and the nice job it does !
