Fantastic Grinder for a single use! I used this grinder to grind up some spices the day i received it about 3 months ago. Unfortunately once the lid was done up i havent been able to undo it.
Because the unit is round and smooth you cannot grip it easily and so cannot grasp it properly to open. Very unfortunate. The one time i did get to use it, it worked well. However that was the last time.
