Starting my Festool sander collection

Bored and trolling?

Doesn't it rather depend on the tasks one has in mind?

If a number of projects are contemplated for which the corner tip of the sander is going to be used heavily and repeatedly, the the RO90's pad (and abrasives) in the shape of a Reuleaux Triangle (that is, an equilateral curvilinear one) with its three-way symmetry could be a factor worth considering. But then so would be the cost of the dedicated abrasives. Also, remember that the pad can also be rotated if the tip gets too worn.

I don't have an RO90, but I tried one at a Festool Roadshow and whilst, yes it is bulky for the pad size, and seemed mostly to require two hands, it was - on first acquaintance - a good deal less unruly than I'd expected.

  I will agree with that. the RO 90 is not unruly, even in Rotex mode with aggressive grit paper installed. My only complaint with mine is that I don't like the performance of the Random Orbit Sanding mode, so I rarely use it in that mode unless the pad size is just right for whatever I'm sanding. Actually bought a Metabo Sander that's slightly smaller in pad size to use as my dedicated 'small' round pad ROS. And the option of extending the Delta pad even further away from the sanding head with the accessory from Festool that mounts it that way, is another nice-to-have item for hard to reach areas when using the RO 90.
