Positive Product Points
It's a monster This is for the MDX I did not see a thread for it or see how to start one. The mods may move this to a MDX thread i hope it would be nice to see. This thing rocks. It blasts out perfect grinds with a very unique method of adjustment.
Negative Product Points
It's a monster I think it is more of a true industrial or commercial machine than a home machine. It is for high use high volume and may not be easy as a couple of shots a day grinder because the doser holds so much even just as loose grinds spread around.
Just picked one up used. it is a comercial grinder but I would say more like an industrial grinder. The thing is huge and powerfull. I jumped up from a Rocky and had a lot of choices but since I like my Nuova Simonelli espresso machine I thought it be fun to try this one over some of the more popular ones for home use. The first thing I can say is the grinds come out at 100 mph hitting a small plate and metal hook before smashing on the back wall of the doser. I now see why you need a doser it would fly all over the room without it. The grind is 100% even and clump free. The doser feels heavy to use but hits the portafillter pretty good. The first shot was amazing. The extraction was perfect and I never seen my espresso look like that in the cup. The bean hopper is massive but has a stop I find I can open the stop to fill the grind area and have enough beans to make a shot. It can also be removed. I think you could just use a cup as a mini hopper if you wanted. Mine sits out on a open counter. It will not fit under anything. The doser is huge and a little tricky to sweep clean inside because of the half cover for a micro switch that turns the unit off when it is full. I may make easy to take off then I can brush it easier because the machine blasts the coffee everywhere in there. It has an interesting method of adjusting. The bottom burr moves not the top. You can pop the top burr off to clean and back on and never change your adjustment. Most others you have to spin the top off and then back on until you find zero then re adjust. The adjustment is so fine it has two sets of numbers. I started with setting it at zero and then set the numbers and got pretty close to perfect on the first try. The doser is also adjusible from under it so It is easy to change on the fly and seems to drop the dose into the portafilter very gently. This thing gets it done.
Took a chance on Ebay all the parts are easy to get so no matter how used it is it can still work like new for under $100.
Three Month Followup
After 3 months I still feel this machine is an industrial grinder. It is well suited for grinder that runs all day in a shop. For home use I removed the top plate that would have held the shut off switch when the doser is full. By removing this assembly I can easily use a brush to clean grinds that stick to th sides or stay in the chute from the burrs. I am going to guess all grinders will have grind stay in there between doses so its nice to be able sweep completely clean between doses. Another nice feature is the hopper has a stopper. I use that to drop enough beans for one dose. It is a rough guess at how much to dispense but I measure the dose by weight in the portafillter. If I wanted I could remove the hopper and put an open end cup and grind a pre measured dose or different coffee at a time. The feature where the top plate and burr can be removed for cleaning without changing the adjustment is nice and unique to this unit. I find a lot of coffee dust on and around the grinder after some time of use but I guess you need to clean once in a while. Living in Miami and looking at grinders in Cuban coffee bars they are surrounded by coffe dust and the machines look like they have never been cleaned. For the most part for using giant industrial machine for 15 grams at a time it works ok. The doser is a bit stiff but I doses clean. I do not have leftover grounds in the doser bottom. Also the doser comes apart easily to clean. I bought new burrs for it just because they were not too expensive and easy to change. Being a used machine I did not know the history and it looked well used. The adjustment system is spot on. It has numbers on the base and dial and in most cases when 0 is on 0 the grind is perfect. Small adjustments are easy to make and see on the indicator. In summery it may be a little more of a work horse than I needed but it is well suited for micro barista. The burrs and machine is built by Eurika and if you look at the Eurika line they are the same machine but with a different styling that is kind of cool.
