Basic blender went bad (motor ran but spindle wasn’t rotating). I wanted to disassemble to see if it could be repaired. Three of the four screws were Phillips head. I had to cut the casing open in order to discover why I couldn’t unscrew the fourth. It was a slotted spanner.
The security bit is doing it’s job. If this is a barrier for someone, then they aren’t the kind of person who should be playing with the internals of a dangerous electronic device.
Shit take.
