Rated 4.8 out of 5 by 5 reviewers.
Rated 4.0 out of 5.0 by A great sander! I've run this sander about seven hours, almost constant. The ergonomics are great. I especially like that it is not top heavy like the old Porter Cables. I have run belt sanders for a lot of years (both in the building trades and as a woodworker) and this tool impresses me as well designed. I did not use the dust collector, but hooked it to my shop vac and was pleased that it did so well in catching the dust. With a forty grit belt this baby will really move some wood. I would not buy the one with fewer amps as with a coarse belt one can overload this one, if you push down. (Which you are not supposed to do.) As to quiet? You need ear plugs. I think getting one of these for bigger jobs, and then the Porter Cable tiny one is a good combo, better than buying one 3 x 21 sander, if you can afford it. But both of these sanders have a weak spring for the belt adjustment. Bump it and it turns, sending the belt off track. So, it may take getting a heavier spring, no big deal. The four stars is because of that. But also, I ordered it online from HD, had it sent to my house to arrive just before a big project. But it arrived used. No kidding, you could look into it and see sawdust down inside it. I examined the platen and could tell it had little use and as I needed it, I did not return it for a new one. So, understand that HD may send you a used one, just like Amazon. However, with Amazon many report missing pieces and defects and this one was fine. I do appreciate that we can return these to the local store for returns. BUT, it only seems fair that one can, or "demo", and get a five dollar discount or whatever for it being used.

Rated 5.0 out of 5.0 by Excellent Belt Sander I looked at belt sanders for several months off and on before purchasing this belt sander. I am one who reads reviews of tools before I buy, taking into consideration the thoughts and experience of those who purchased this sander before me, before I made my purchase. I have to say this belt sander has plenty of power, is smooth sanding, whether using super coarse 36 grit up to 100 grip belts. It really does an incredible job! If you read the reviews on the Porter Cable sanders, you will find four issues described by several users with them. Those include bad dust collection because of the type of connection used to connect the bag to the sander, a double spring clip, the platten overheating and warping causing gouges in the wood, inboard mounted bearings directly in the path of dust, etc. Porter Cable no longer manufactures quality industrial tools, rather choosing quantity over quality in their marketing campaigns to home users instead of the industrial market. Quite a change from making the best belt sander on the market, the 503 Locomotive. So, if you are looking for a 4 x 24 belt sander that will run and perform well, look at this sander and strongly consider it. Speaking of dust collection, you will hardly notice any dust as this sander picks up 99% of the dust. Only a small amount was left behind the sander and on the work bench. Excellent dust collection indeed! I truly believe in sharing information with others when I have had excellent results with a tool. This sander is built exceptionally well and performs well and I am glad I passed on the Porter Cable. January 6, 2015
Rated 5.0 out of 5.0 by cut sanding time bought this to sand rough cut oak as i was making a cutting board. easy to use, plenty of power. long cord is really handy. dust collector works well. October 23, 2012
Rated 5.0 out of 5.0 by Great Sander! Had been using a less expensive Black & Decker sander for several years and finally got decided to buy a more powerful, easier to use sander. This Makita is excellent - cut my sanding time in half (or more) March 11, 2014
Rated 5.0 out of 5.0 by Great tool! Great tool! I also have the Porter Cable 3x21 belt sander. The makita 4x24 covers a larger surface area and is great for leveling large glue ups such as table tops. February 18, 2014
