Jim and others,
First, I believe that
the Lelit PL53 is a breakthrough in performance for its price point -- a bargain with fixable problems. When I put on my marketing hat, it shows where there's a "hole in the market" and that it's possible to offer an actual espresso grinder for a more reasonable price. Probably many people give up pursuing an espresso hobby because they can't afford it, so lower price could achieve higher sales volume and more foodies taking on this hobby. I've created another post suggesting that people may be able to find starter machines much less expensive than the Rancilio Silvia, for instance. (See
For low budget is Saeco Magic Cappuccino Plus much different than Silvia? Back to the Lelit PL53, which I bought as a refurb, I'm going to keep it and am using it to get pretty good results. And no way can my wallet or marriage afford $350 for a grinder during this Great Recession!)
Usability SuggestionsMy usability suggestions are intended to direct the manufacturer's attention through Jim, their U.S. rep, beyond functionality of the grinding mechanism and its attractive, compact appearance to what's needed to make it easier and less messy to use. Such modifications in a future model shouldn't be expensive to do, and they'll eliminate many hassles.
These aren't "complaints" about a bad machine but suggestions for improving it.Tabs. If it's going to have tabs for positioning the portafilter, make them adjustable. Otherwise eliminate them. There are a variety of portafilters out there, both 53 and 58mm. Some have handles attached in different ways. The handle for mine and its 53mm size make it deeper than is allowed for with the tabs on this grinder. I'm not the only one who's posted needing to catch grinds in a cup. I don't see much need for a fixed, guiding tab for a portafilter anyway. If you can hold it under the spout while pressing the start button there, who needs training wheels? The start button is correctly placed just below the top edge of any portafilter, and that's all the guidance that's needed.
Hopper. This is a solid, high quality grinder with an extremely flimsy, thin plastic hopper. It would be great to have a metal replacement available and for new models to have a higher quality hopper. Already the bottom edge where my hopper enters the grinder is chipping off. This is kind of like buying a Harley fitted with Vespa scooter tires.
The use of a cap at the bottom of the hopper as a finger guard makes sense. Thanks, Jim, for explaining that. If I had kids in the house, I would leave it on. I appreciate that there are screws that hold that cap in place so it can be easily removed, which I've just done. I'm getting good results using my dark roasted, oily beans, BTW.

I found another workaround too. If I wanted to keep the cap on and make dark roast beans feed more easily, I've had success mixing in a small amount of a lighter, non-oily roast, not very different from the espresso talc suggestion I'd thought of earlier.
Chute problems. About difficulty removing the chute for cleaning, there are countless posts on this site emphasizing freshness of grounds. Anyone who wants to make a high quality shot would like cleaning the chute to be as easy as possible. I'm not the only one who has posted about the extreme difficulty of replacing the chute once it's been removed. I'm 6'3" and in good shape. It takes every bit of hand strength I have to oomph the chute into place. This is a design oversight. It's compounded by an unusually long set screw. I'm surprised the engineers at Lelit didn't take the time to figure out a way to make the chute easily removable and replaceable for cleaning. I don't expect my machine to be fixed (no need for a Toyota recall!). But I'm suggesting that this feature be improved. All it takes is moving the location of the screw hole and having a larger gauge, shorter length set screw or better yet, some clip-on feature. But one only knows the difficulty of using this feature by using it. Apparently they didn't do so.
Static? Here, perhaps Jim and others can help me. I'm not surprised or flustered by static build-up. Isn't this something anyone should expect when you're creating friction by grinding? Does it make a difference if it's a refurb or new or better machine? How do other machines or other people deal with static build-up, if they do so at all? I just tap the teacup until the grinds shake loose. Of course if I could directly fill the portafilter ...
