Wish I would have pulled the trigger on this purchase years ago. I finally got fed up with belt sanders. Tired of having to watch if the belt is drifting. Tired of replacing perfectly good belts, other than the glue strip/tape came loose. Tired in general, because a belt sander is tiring. I knew that I would be removing a lot of surface wood, and was trying to think outside the box (grinders/mods, polishers, multitools...). After looking at the options, just couldn't pass up this versatile inexpensive tool from a reliable manufacturer. A cordless version wasn't available when I made my purchase, which is good. Something like this when sanding with coarse grit will use a bit of power. With 40 grit, it is way easier to control than a belt sander. Haven't used fine grit yet, but with the adjustable speed dial (If you're wondering, the speed dial is round and built into the trigger - very convenient), the speed can go much lower and much faster than I'll ever need. If you need to go slower than this, then you might as well use a hand pad. If you need to go faster, then you might want to use a grinder. This tool fell into a sweet spot between price and functionality. Hindsight being 20-20, I feel very satisfied with this purchase. Also, looks like it would be easy to convert to 7" discs, if the need arises. The 5" discs cost about $1/each, which is much less expensive than crappy belts. The range of capability appears huge within this $80 tool. No more belt sanding for me, plus I'll be able to do a lot of fine work with it too. Prior to this purchase, I dreaded sanding. Now, I'm almost looking forward it. Even better, I'm not avoiding sanding. If you're reading this review - go buy it - you'll like it. I'm not affiliated with Dewalt. I've just been so impressed with some the Dewalt tool time saving ergonomics, that I use Dewalt as my standard. For cordless, I pretty much only use Dewalt (So that I don't have to buy more batteries). My first Dewalt tool was a marked down returned portable table saw, quite a few years ago; best tool purchase ever, by far. This Dewalt sander has potential to become my second favorite tool purchase, and for a lot less money.
