Why does LUME grinder's burr wobble?
Our new pro users will soon discover that LUME grinder’s ceramic burr is slightly wobbling when rotates. Also the burr outer-ring is movable as demonstrated in below two images.
There is a simple explanation for this - we discovered in our lab tests that a “controlled-wobbling” is compensated by the consistent torque generated by the grinding motor. Therefore the ground quality won’t suffer. This design in fact will allow buffering for the rotating shaft further extending battery life by up to 25%.
Due to this unique engineering design, you MUST place LUME on a flat surface and do not shake or move it around during the grinding process. Otherwise ground consistency will be affected.
