Looking for something more aggressive than my PC333VS, but more "civilized" than my PC352VS, and after trying out the Ridgid ROS2610 (see this thread), I decided to bite the bullet and pre-ordered the new Festool RO150FEQ. Bob Marino took care of my order promptly.
It got here yesterday and I tried it out last night, sanding the drawer fronts for a captain bed I'm building. I can now declare the RO150 is a keeper .
Dust collection is as good as it can get. I hook it up to a Fein Mini-Turbo with a Craftsman auto switch plugged in a 120V, 20A outlet. The dust port on the sander is round, 1" outside diameter, same size as the dust port on the PC333VS. The PC vacuum hose fits perfectly (so does a Fein step-down adapter). There is no dust in the air.
In terms of noise, the RO150 is a bit louder than the PC333VS, about as loud as the ROS2610 (no, I don't want to compare anything to the PC352VS ).
But it is smooooth. Even with the Mini-Turbo at full speed, the RO150 is very easy to control. In fine-sanding mode, I don't need the front handle. In coarse-sanding mode, the front handle helps significantly. Interestingly, I feel more vibration from the front handle more than from the main body handle. Note that the main reason I returned the ROS2610 is its jerkiness when connected to a shop vac.
I don't have any other Festool tool (yet ), but I can see the benefit of the removable power cord from the sander. If I need to use another Festool tool with dust collection, I can just unplug the power cord and the dust hose from one tool and plug them in the other - very convenient.
Since I spent a significant amount of changes on the RO150, I think I'm entitled to some nit-picking
1. The user's manual is adequate, but not as detailed nor of high quality as the ones from PC or Ridgid. The section on "Sanding motion" has a (correct) picture of the RO150FEQ, but the (incorrect) wording is lifted from the manual of the old RO150E.
2. The body of the sander feels warm after a few minutes of operation - not untouchable, but warmer than any handheld sander I've used. To make sure it is normal, I sand continuously for 30 minutes. The sander does not get warmer and there is no problem.
All in all, the RO150FEQ is highly recommended, as is Bob Marino's service.
