ENDURATECH Motor for Improved Productivity and Durability
The 2008 winner of the WOOD Magazine Top Tool Award, the 390K boasts ENDURATECH brushless motor technology for 70 percent fewer wearable parts, which increases the motor life by up to 10 times when compared to traditional palm-grip sander motors. The result is greatly improved productivity, durability, and control.
Low-Profile Design for Optimum Control

Innovative Brake Designs Save Time and Reduce Free-Spin
Also, the 390K saves you time with its innovative electronic motor brake, which reduces spin-down waiting from close to 10 seconds to approximately 3 seconds.A separate mechanical pad brake reduces free-spin--effectively putting an end to gouging, and a 3/32-inch orbit diameter means this sander can handle a range of materials with ease.
Compact, Ergonomic Design with Integrated Dust Port
The 390K measures 4 by 5 by 12 inches (W x H x D) and weighs just 2.1 pounds, so it's compact and easy to store. Its rubber grip and ergonomic features maintain user comfort, even during extended jobs.
For further convenience, an integrated dust port accepts 1-inch and 1-1/2-inch vacuum hoses for optimal dust collection. This makes your workspace cleaner and healthier and helps maintain good visibility of your workpiece.
The 390K is backed by a three-year warranty.

Pros: Lower center of gravity makes it a delight to use. Feels more natural, like a sanding block. This is a very, very powerful sander, and the constant response motor prevents the sander from bogging down with pressure--no matter how hard or soft you apply pressure to the workpiece, the power is always there. The quick stop feature is a great innovation--you don't need to wait for it to stop or use a "sander sitter". The benefit of all of this is that you get A LOT of sanding done in much less time, compared to other 5 inch orbital units (e.g. Bosch).
Cons: (reason for 4 stars and not 5) Two, that are greatly overshadowed by the PRO's above, but issues nonetheless. The biggest problem is the receptacle for dust collection. It only takes that stupid Porter Cable dust hose that is horribly inefficient due to the small size of the hose. The hose is functional and does suck up dust, but could be better. I had one of these hoses laying around from my biscuit cutter, but it is still a lousy design. Maybe I can Jimmy up some type of setup for a better hose with an adapter.
The next con is that the top of the unit is somewhat broad and a little difficult to "palm" without some hand fatigue, but I am getting used to it. This ergonomic shortcoming is somewhat compensated by less fatigue by the lower center of gravity, but not entirely. The more standard units have a smaller top that is easier to get your hand around.
I would definitely buy the item again. It is a very useful tool.
I love the electric brake; it makes changing sanding discs much quicker. My only complaint is that it doesn't seem to have quite the guts of the Bosch. I'll have to do some side-by-side tests when I've got some time to play, but my first impression is that it takes a little longer to do what I normally do. I don't understand how this could be, because the amps are comparable, as are the orbits per minute. It's possible that it's so much lighter and less bulky that I just think it's not as aggressive. I have a normal deficit of patience and I have a hard time making myself turn the Bosch down, even when I know I should. So maybe having a slightly less aggressive machine will save me from myself. I know my shoulders like it better.
All-in-all, I think it's a great sander. And I don't think you have to have large hands to use it comfortably.
