    Laser cut shower screens.

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Wondering if anyone has tried these yet Precision Shower Screen - E61 - YouTube laser cut shower screens.

    Are they an improvement or simply pandering to the geeks among us?

    Yelta, I have one and use it on my Profitec (and formerly on my ECM Technika). I think it cleans up more easily than the stock shower screen, but otherwise see no difference in the cup.

    I have one mounted in my main espresso machine and I like it. It's difficult to say whether a typical shot is improved with this screen -- that will be dependent on a lot of other factors -- but it's clear that less gunk collects in the group head behind the screen. Cleaning sessions can be less frequent with it in place, and that is a nice feature.

    And, by the way, there's nothing wrong with pandering to geeks, is there? ;-)

    I use one and it does seem easier to keep clean(ish).

    I'm fortunate in that the Galatea is a breeze to keep clean, seems I would gain little by changing the screen.

    We've been selling them for a year or so Shower screen IMS competition | Talk Coffee

    They're beautifully made and not too expensive. In all likelihood, they may deliver little other than placebo effect, but they sure look and feel good.

    Groupheads shower screens are precise enough...

    Getting lasers to cut your groups showerhead is almost overkill.

    But it may direct water more precisely and evenly among the puck....... Nice find

    Hey Chris, do you know if there is a version of these that fit silvia groups? I've used them on La Marzocco, not sure if the LM ones would fit a silvia? I feel like the benefit of these might be greater some machines over others depending on the water dispersion setup in the group?

    IMS cater for many different brands. I have E61, LM/synesso/slayer, rancilio, cimbali, san marco and Nuova Simonelli variants.

    Not tried them myself yet but a friend has then on his machine and believes they are worth the money, and he has lots more knowledge re coffee than me.
    I guess it depends on your personal skill, preferences and palate if they make a difference or not.

    And for the geeks among us (WHAT??? Coffee geeks talking coffee on a coffee forum) who like the VST or EP Pression style of basket then it completes the set then doesn't it. No point being that exact at one end if not at the other

    Well actually, when I used them on LM's they didn't really change the flow rate or have much of an impact on how the coffee extracts.

    VST's make a much bigger difference.

    Have yet to see anything in this thread that has convinced me to invest in one (laser cut shower screen) I deliberately refrained from mentioning baskets by name, seems others are unable to show the same restraint, I guess a plug is a plug.

    The biggest difference one can ever make to the coffee they drink is to get the grind, dose and tamp right.

    Same thoughts here Yelta
    Might get to play on a LM Strada with them installed soon.
    Would be interesting to have a 2 grp machine, one with laser screen installed and 2 grinders of the same make to play.

    Brought one and didn't make much difference in taste that I could tell. But it's easier to clean as it has no mesh.

    Owners of the Lelit Mara PL62 have bought this screen, since it seems to keen the machine internals a lot cleaner. You can see this clearly from the water the 3-way valve releases into the drip tray. More details in the Mara Owners Thread.

    Compared to the stock screen the water distribution is much more even with the IMS. When I installed it I felt that I was getting a more even extraction and a slightly cleaner taste. Was I imagining this? Well, I don't think so, but I concede that it was subtle and something that you quickly become used to.

    Like Steve, I thought it was well work $30 + postage for the cleanliness benefits.

    If you soak your old screen in backflushing powder and boiling water for like 30 mins and get rid of all the coffee residue behind the mesh, the taste is just as clean. But its a pain so I rarely clean it that well... This one takes the fuss out as there is no mesh. That in itself is worth the small investment... much cheaper than other upgrades

    Also I highly doubt it keeps your internals any cleaner. If you don't water backflush and take off the filter after pulling 6 shots... there is similar amounts of coffee residue behind the screen to the old screen. Give it a go.

    I think you may be right Yelta. I am not convinced it will make a world of difference, but nevertheless I am a geek so I have to get one now (look what you've done to me haha). The Galatea is certainly a breeze to clean. I still pull the shower screen basket out of my Galatea daily to give it a good clean, but if these screens improve on cleanliness I am sold. The placebo effect might kick in too if I am lucky But I think chokkidog hit the nail on the head on what is important.

    I am glad you stock these and for such a reasonable price too Chris . I'll be investing in one soon.

    Reviving an old thread but... my main interest is in whether these avoid build up of coffee residue and grime behind the screen.
    Even water flow seems likely on most new shower screens that are clean.

    So what's peoples experiences of coffee build up in these IMS screens ? (assuming you are cleaning your machine regularly) :-)

    We have a couple of Wega two group machines in our training room which we have fitted with IMS screens. With a good clean of the dispersion blocks with a brass wire brush we are seeing, I think for the first time, how a shower screen should deliver. I often think that great coffee is a game of 1%'s even if this is only 0.5% it still makes me pretty happy.

    Mine has been great. I pulled it off just the other day. There was a very fine film on the back of the screen and also the group. This is with water backflushing after each session (usually a single shot) and caffetto backflushing every two or so weeks.

    The beauty is that a quick wipe and it's as good as new. The previous screens always collected stuff between the mesh and the solid backing no matter how well maintained. The IMS is single later do nowhere for stuff to stick.

    If you need a new screen I would grab an IMS, it will probably last a lifetime with domestic use.

    One negative is that the indent is quite shallow. Using a spoon to leaver it out it takes a few goes to get it out (spoon slips out of groove). No biggie but an observation.

    Cheers

    I have just put an IMS screen on for the first time, and I agree the cleaning is really nice and easy.

    I have noticed that when I pour water through the screen with no pf fitted my brew pressure gauge shows 4bar. I don't remember this with the stock screen, has anyone else noticed this?

    Interesting. My brew pressure with stock screen and no PF is around 2 bar. Will have to get my wallet in to gear and place an order for one of these IMS screens. Test it out.

    Totally normal...

    Happens because the Pressure Gauge is tapped in upstream of the Group Gicleur...

    Worth it for the cleanliness factor alone i'd say. Distribution is much more even too. AND its super shiny haha.

    Installed one today on the BZ10; can't say i noticed anything different in the cup after one (but that was a decaf =) )

    No tripod, but you get the idea
