  • Balanced, quality, weird dust extractor horn location.
This is a very well balanced, and high-quality sander. The only flaw is the dust horn is a super awkward exit to the right side, which limits edge sanding on one side, which is the whole point of having a sander like this. If Bosch could redesign the dust horn to come out straight back like almost all the competitors do, this thing would be absolutely perfect. ... show more

  • Very versatile sander!!
Bosch make some of the best Sanders on the market, this one is no exception. Build quality is excellent. Very comfortable to use with low vibration. I didn't realize I was going to get three different sanding pads with this sander. This makes it even more versatile. Dust collection is excellent. Would highly recommend. ... show more

  • I use Gator PowerNet Detail Sandpaper for the pointed mouse shaped pad
This is an excellent detail sander. However, as others have said, no one, including Bosch, seems to sell sandpaper that fits the mouse shaped sanding pad. The Bosch sanding papers I found on amazon.uk are the correct shape, but the dust collection holes do not line up, which makes the sandpaper basically useless. However, I found that Gator PowerNet Ceramic alumina Detail Sandpaper basically fits the mouse shaped pad (it is a little small in length) and is a mesh design, so the dust collection mostly works. ... show more

  • Great sander, except where to find the sanding paper?
This is, for the most part, a great finishing sander. It's lightweight, easy to operate, and versatile. The battery life is excellent (when used with an 18V Core battery), and the material removal is very controlled. The dust collection is surprisingly very effective as well (for a "sock"). However, it is virtually impossible to find sanding paper for the machine. Additionally, the clamp-on mechanism that accompanies the 1/3 size sanding plate is a terrible design. It is, in fact, so bad that it's just about useless. That leaves you with but one option: buy a non-fitting hook and loop paper somewhere and adapt it to fit this sander. Bosch, I am German, and I am ashamed for you. ... show more

  • Great with a flaw
Initially I really love this but after using it a week dust port on the side beats the purpose for this sander. It blocks when accessing corners. It is still better than any other cordless finish sander but I am returning this to get a corded festool rts.
