The L2 will be reluctantly leaving my possession to move on to the next person today. It will be missed.
Right out of the box this grinder was extremely impressive. The design is gorgeous, and with the other OE grinders, it is built like a brick outhouse. Aesthetically, I don't the grinder could have be designed to look any better.
I like the adjustment mechanism better than the L1. It's nice not to have to remove the jar and fiddle with a coffee coated screw and nut in order to make the adjustment. To be honest, I used this grinder almost exclusively with me new Ponte Vecchio Lusso. I did adjust it out to a pour over setting once, but then moved it back to espresso. The L2 did choke the machine a couple of times, which I did not get the L1 to do but once. I can tell the grind from the L2 was more fluffy and consistent.
I also loved the grinding handle. It's now much easier to dump coffee into the grinder. I did think the black knob on the grind handle was overly stiff and awkward. I think if the L2 could be modified to allow that knob to move more freely, grinding would be much easier overall.
I did do one small modification while in my possession. Although the grinder is easier to adjust, I don't really see the purpose of the tick marks on the locking nut that you loosen in order to adjust the grinder. I also don't see why the adjustment nut has marks all the way around it. I think all is need is the single black tick mark on the adjuster and tick marks around a stationary portion of the grinder. With those ideas in mind I ended up taking a thin piece of masking tape and lined it with a tick mark every 5mm:
After applying the tape I found the "0" point of the grinder (marked by a 0 on the tape), or the point at which the burrs touch but you could still turn the grinding arm, and adjusted out from there . Using the tick marks on the tape and the black tick mark on the adjusting nut, I was able to find a sweet spot for a particular brewing method, adjust it for another brewing method, and the return it to a previous setting easily.
Overall, I highly recommend this grinder to anyone willing to pony up the dough. It's construction and performance it top notch.
Pros:
Beautiful grinder
Much improved design over L1
Excellent grind quality
Cons:
Grind knob seems stiff
Awkward screwing grinder on the jar
Grind retention.
