The release on the saw dust collection bag is not a zipper but a slide device which works nicely.

The first thing I noticed was it's incredible balance and precision, obviously well designed and built, has a very "solid" feel.

I am so glad that I bought this one - it was worth every penny, I would definitely buy it again, and the floor looks great.

I have replace a 20 year old Craftsman belt sander with the 9903 Makita. I always fought with the Craftsman's tracking. I could only go 5 minutes before I needed to adjust the tracking. The Makita is not like this at all. It has perfect tracking! I pulled the 9903 out of the box and it tracked OK with the stock belt. But when I put a 3M belt on it and tweeked the tracking a bit I have not touched the tracking, even when I changed the belt to a different grit.

I highly recomment this belt sander and 3M (purple) sanding belts. You can turn 9903 over and clamp it to the bench, great feature. It has a very nice trigger lock button, easy to set when you want to set it - but not so easy to lock when you don't want it locked (with either hand). An added benefit is that this belt sander is that it is very quiet (as belt sanders go).

My only complaint is with the availability of accessories. I can't find a sanding frame or a vacuum attachment. When I went to an authorized dealer for Makita and asked for a quote on a sanding frame they quoted the housing of the 9903.

Buy this one, you won't be disapointed.

I bought the 21" Makita 9903 Belt Sander after my old Skil 18" sander's on/off switch stopped working for the umpteenth time, and my other el-cheapo 21" belt sander was stolen (thank goodness for small favors).

I've used the sander now for a month to sand down 2x6 and 4x4 rough sawn surfaces on redwood and doug fir I've used for finishing a deck (railings, fascia, stair trim). Absolutely perfect tracking all the time, no matter how hot the belt gets, no matter how much pressure I apply, no matter how long I've used the belt. I start with a 50 or 80 grit, then shift directly to a 120 grit belt for final finishing. I've sanded approx. 20 4x6 16 ft boards, both sides and edges, plus another 10 4x4 8ft posts... all 4 sides, among other things this far.

Power galore and perfect belt tracking, simple adjustment to bring belt to edge if needed (and it stays there)... what more could a belt sander need to do? Changing belts is just as simple as with any other belt sander I've used over the years --- pull back on the clamping lever (it says open), slip belt on, close clamping lever... and let 'er rip.

I also very much like the flat 'top' which allows you to turn the sander over and sit it on it's 'top' to use the belt surface as the stationary member while holding the work piece by hand to shape edges, corners, etc. with much greater precision of cut (hand held piece, as opposed to holding the sander).

I also own a Makita sawzall (or whatever they're called) and have owned and used it extensively for several years (purchased in 1992? or '95? or somewhere in that time-frame). It's been extremely reliable, never any problem in the most demanding work I have thrown at it...

A pleasure to use. Relatively quiet. Belt tracks flawlessly. Adequate power. Can clamp upside down in a wood worker's bench vice to use as a stationary sander. Dust collector works well and is usually not in the way. Wish it came with it's own case. All in all I am very happy with the purchase.

This sander has plenty of power for its size, and the vacuum bag actually sucks up quite a bit of the dust without spraying it right back in your face. Tracking is decent and the fact that the right side and top are flat and ready to be clamped down to any available surface makes it great for occasional bench sanding.

What I don't like is how off-balance it is--it really likes to roll toward the left on account of the motor's weight and it's pretty hard to tell whether or not you're holding it level until it's too late. Compound this problem with the fact that the optional sanding shoe/frame is both $114 extra AND discontinued and you've got some pretty heavy cons. I made my own frame out of 3/4" MDF, but it's obviously pretty heavy and not especially durable.

I also have a problem with the placement of the speed adjustment knob--it gets coated in dust almost instantly and becomes impossible to read without a shot of compressed air. I worry about how long it will last before the potentiometer fizzles out.

There seem to be an awful lot of reviews of belt sanders from all manufacturers where customers complain about Amazon shipping them a used unit as new. I too suspected this had happened to me upon opening the box as mine was covered in what appeared to be sawdust. A closer inspection however revealed that this was in fact just cardboard that had gotten sanded by the belt as the unit was thrown around during shipping. No harm, no foul.

If you plan on doing a lot of leveling, I'd consider the DeWalt as you can pick up their frame just about anywhere. Otherwise, there's quite a bit of bang for your buck here. It looks boxy and awkward, but those bad looks really add to the versatility of the machine.

UPDATE: Just talked to Makita on the phone and they confirmed that the sanding shoe accessory is no longer being made by anyone and they have no plans to design or produce a replacement model. Boo.

I gave up on belt sanders years ago after several cheap ones gave me trouble to the point of tossing them. I've been using a power planer since, until my wife suprised me with a new fridge that was 1/4" too tall. The planer has a hard time getting in tight. I got the 9903 and took it out to the shop to fine tune and learn it's personality. I didn't need to; plugged it in, hit the trigger and it just tracked straight with the belt that was on it. It's a little heavy, but not so bad that I can't use it overhead. I'm used to a lot of dust with these things, but very little isn't trapped by the bag. A good buy out of the box.
