Excellent sander, but some shortcomings Aug 22, 2008
By Stephen J. Soldo Intrigued by the design, I purchased this sander. Overall, I am very pleased with it. Here are the pros and cons:
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.

Rated 4 1/2 stars Oct 04, 2008
By Clyde Bouley
"CWB"
I just received my orbital sander (Porter-Cable 390K) a few weeks ago. I bought this sander based on a review in one of the recent wood magazines. Removed it from the box, put some sandpaper on it and away I went. I sanded Oak, Pine and Popular. I used 80, 120, 150 and 220 grit sandpaper and was pleasantly pleased with the results. My biggest concern having my shop in the basement was dust. I've got three other orbital sanders and had to do all my sanding outside. But that is not the case any more. I tried the sander with the dust collector on and then with my Shop-Vac. The dust collection in the on board collector was very good just a small amount of dust left on the bench. For very small, short jobs I would use this method. For larger, longer jobs my Shop-Vac will be used, from what I could tell there was no dust left behind (in both cases if I wiped my hand a crossed the board and there was wood dust. The dust I was talking about was on the bench and in the air, boards have to be whipped clean with a tack cloth. This is one of the few electric tools that I can use the Shop-Vac 1¼ "hose with no adapters and it works like a champ. The noise is very low and the vibration was low also. I wear a medium glove (my fingers are a bit short of the ends) and I found this very comfortable to use. I had complete control and the low center of gravity made it very maneuverable. On high speed this was very aggressive, thus the advantages of speed control and a light touch. I would recommend this sander to all. Overall the only problems I see is the little dust left behind with the on board collection system and price (time will tell if the price was worth it). By the way my other sanders are in storage until I need to do sanding outside.

Definite improvement Sep 18, 2008
By John E. Dinger This review comes about after 10 hrs of real world use of the new sander. The best new features are the quick spindown and the variable speed control. I'm a professional cabinetmaker, and I use the sander to sand between finish coats as well as typical usage. The low speed helps control burn through on flat surfaces and narrow edges using 320grit. The low profile and slight increase in power are the second best new features. The only thing I'm not crazy about is the width of the grip. I have an average hand size and it's a bit wide and not what I would call ergonomic. I would have also put the speed control in a easier to reach place, so that I could control the speed with the same hand that I'm sanding with. The ergonomics become more of an issue when a vacuum hose is hooked up to the sander. It's that little extra pull of weight that makes the job more tiring when your sanding for multiple hours. It's also worth noting that the sander vibrates less that the last version and is a couple of decibles quieter that the 333. I would have given five stars if the sander were more ergonomic.

Like it a lot Oct 09, 2008
By Lorraine S. Stanley I'm a little baffled by the reviewers who said this sander was difficult to use unless you have large hands. I'm a 5'7", 125 pound gal who has what I think are normal size hands for the rest of me, and I have no problem at all using this sander. It's much lighter and less bulky than the machine I've been using (a Bosch). I work on wooden boats, and I think this is a great addition to the tool closet. The dust port is easy to hook into our existing vacuum system. It's one of the better adapters I've come across. I like that the speed adjustment dial is where it is. I hate turning the sander speed down inadvertently, just in the course of using the machine. This happens regularly with my Bosch and it drives me nuts. If I do want to adjust the speed, it's not difficult do so.
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.

Awkward Sander Sep 14, 2008
By M. Deal I bought this product based on a glowing review in a national wood working magazine. In fairness, they did say the sander required a large hand. Perhaps they should have emphasized the caution of 'large hand'! I found the sander terribly fatiguing and believe me, I do not have small hands. There is simply no place to comfortably place your hand for several hours of sanding. Additionally, this sander is anything but maneuverable due to the size and weight combined with the dust bag holder - it's akin to doing a U-turn in your driveway with a semi truck.
Highly recommend you go to a store and try this sander before ordering.
