Positive Product Points
grind quality from flat burrs safety lever disable the moter when bean hopper is not in place heavy
Negative Product Points
tamper automatic switch activated when the hopper is half full close design doser step grind adjustment
BEAN HOPPER capacity : 1kg. it comes with a sticking out fin to activate a safety switch. it has clumsy and loose aluminum blade to close the funnel in order to take the hopper out with beans inside the hopper. but be careful.
GRIND ADJUSTMENT though it has step grind adjustment, but the thread of the upper burr is pretty fine. to adjust one step (half the number) doesn't give much different. it has numbers and visual cue to which direction one should dial the top burr. and the top burr fitting is heavy and sturdy.
MOTOR big and heavy motor is located at the bottom part of the grinder. it gets heat up after grinding the whole 1kg at once. the bottom part of the body has two way ventilations. just stick two computer fans on each side would help venting hot air from the body.
DOSER designed for successive use. it has a plastic wall hanging from a ceiling when the grinder is running, the ground will not be spit out all over the doser, but kept inside the wall. this wall has a lever to operate a switch. this switch will stop the motor when the ground is heavy enough to push that hanging wall to operate the switch. the ideal for this doser is to alwasy have a queue of customers, adjust the doser for a 8grms click, then just pulling the lever for your shots. the machine will keep on grinding when it's needed. it is also a counter at the side of the doser. who wants that? i opened up the doser, deactivated the switch to grind per shot. i also cut out the ceiling that cover the doser so that i can swipe excessive ground back into the doser. however, the center of the swiping fins is too big and caught some ground that can't get back into the funnel. need to clean with a brush or get modified like mazzer. it is a cleverly designed doser, but not practical in case of grinding per shot. tamper is a big useless. i took it out.
