Good sander
Works very well. Dust pick up is pretty good for what it is. Definitely not 100%. But I didn’t expect that. Get the shop vac attachment for the best dust pick up. And don’t even bother with the filtered collector it comes with unless you’re sanding toothpicks. It fills up very fast. You’ll be emptying it more than you’ll be sanding. But then you already knew sanding causes a lot of dust and didn’t expect that tiny thing to hold a lot did you? If you have small hands it will probably get hard to hold if you’re sanding a lot and holding it sideways. I think that is typical for these types of sanders though. Very comfortable sanding horizontal surfaces. Highly recommend. Goid deal for the price.

Smooth Performance
Excellent quarter sheet sander. Very smooth and decently quiet. I just completed a massive kitchen remodel and this was very helpful in getting sanding done on the styles & rails on cabinet doors. Top quality construction that should last for years.

Like magic
This sander works great. Can’t say if its better than a DeWalt or Makita, but it works and is easy to use and keeps grip of the sandpaper well. What is really “like magic” is how well it collects the sanding dust. No vacuum hose source is needed – it just gets blown into the canister in back without a vacuum. My 14 yo daughter was using this (that’s how easy it is to use!!) while I was hand sanding, and the dust difference was like night and day. Need to empty the dust canister frequently more so for coarse grit sandpaper, but that takes all of 1 min to do. Well worth the almost non-existent dust and not having to run a vacuum cleaner.

good sander and good dust control
My Makita palm sander I bought over thirty years. finally died I loved this tool, but its one down side was It had no dust collection system other than a cloth bag that was useless. So when I went looking for its replacement, I wan’t something with a decent dust collection system. After reading through tyhe reviews of all the major brands, I had concluded that still none of them had a decent dust collection system. I decided on the Bosch Palm sander simply because I have a larger Boscg sander with pretty good dust collection, and hoped for the best with the Palm sander. When ther sander arrived and I gave it a test run I was delighted with the dust control it provided. I immediately got rid of the dust filter than came with the sander and hooked it up to a dewalt shop vac I have, and the results were pretty amazing. The dust control was better than anything I expected. Nearly any Palm sander nowdays will provide decent sanding, but if you have a good shop vac and can connect it to this Bosch sander (you need an adaptor to get from the sander to the shop vac hose) then you can sand away with little or no dust. P.S. I have been woodworking for 40 years, and I rarely write reviews. But when I find a tool that might benefit other woodworkers, I try to pass on my observations

Excellent Buy
I bought this sander to sand some “bowls” that I had routed out of a cheese board that were too small for my 5″ random orbital. For the price, I don’t think you can beat this little sander. It feels pretty nice in your hand and you can use it for hours at a time without it causing too much stress on your hands. The dust collection is probably the best that I’ve seen for a sander at this price. It’s not Festool level by any means (although a Festool hose will fit it well), but if you pair this sander with a downdraft table, you’re going to be in pretty good shape. I’d still use my random orbital sander for most things, but this is a nice addition to my shop.

Good sander, reasonably priced.
I like having a 1/4 sheet sander for getting into corners, or along straight edges. This Bosch works well and is reasonably priced. No way I could justify the price of a battery operated one which is much more expensive. I like that it has a filter for the dust canister. It leaves more scratches than a random orbital, but that is to be expected.

This sander is very handy for finishing as it uses standard sheets of sandpaper that the included press pops the dust collection holes in. I just cut up a stack of paper in advance of the grits I need and when changing over, pop in the dust collection holes and right back at it.Vibration feed back to the user is good and stays comfortable to use for an extended period. Like my other Bosch tools, I look forward to using them as they allow me to build and finish far above what I was able to do prior. I think the fact they work so well makes you eager to do the best work you can as you do not get worn down my the frustration some other brands deliver.I do wear hearing protection although it is not overly loud, it does buzz along with enough noise that hearing protection is not a bad idea.As typical with all the other Bosch tools I own, this is a very nicely built quality tool that I expect will last me a long time.

Me gusta que no hace mucho ruido al lijar, no es pesada lo único que no me gustó fue que aún suelta un poco de aserrÃn que no logra atrapar el contenedor pero es el menor de los males. Si eso no te preocupa este producto es para ti
