WOT??? Not Bluetooth... Much as I love Fe$tool, I feel it's the Bluetooth feature that puts it in comparable distance with Mirka... but I'm guessing you've anticipated this.
Yes the paddle still is a PITA, as like you (but better looking), I continually get caught out when replacing discs... but I have allayed that fear/scare, I now wear disposable nappies for when the fan is hit.

One thing I hate about Fe$tool (mea culpa, mea culpa, mea maxima culpa... fasting till next Lent) sanders is that they have their own hole configuration directing users towards their sanding discs... thank the gods for Abranet mesh.

If your first cut is too short... Take the second cut from the longer end... LBD
