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.
If you snap one, they will send you a replacement for free. I chipped one of the security torx once, and was surprised at how easy it was to get replaced.
thats whats up!
