IMS Precision 16-18g Filter Basket compatible with Delonghi La Specialista, DL2TH26E

Simple, shiny, and effective. I can easily fit 18g of espresso grinds. The price feels decent for a precision manufactured part. The rim has a slight rounded ridge at the top of the basket, but there do not seem to be any issues with leaks. I would prefer a flat top to better accommodate magnetic dosing rings, but I am generally not turning the portafilter on its side while loading. This is a good piece of decent puck prep, which means it is mostly easy to clean with a good puck. Espresso flow seems a bit more consistent though I would not say the end product is drastically different, at least for me.

This basket feels different from the original basket I received with my portafilter. Materials feel of a higher quality. Fits perfectly into my 51mm portafilter and will not accidentally come out. The holes look more consistent and the water flow looks more even. Definitely an upgrade from the cheap basket that came with the portafilter.

Works like a charm in my bottomless portafilter. I don't have channeling issues in either of my baskets beyond user error so I can't comment on the efficacy of the convex bottom. My only gripe is that the rim flares out so far that it catches slightly on the machine (Delonghi 3420) and it forces you to use funnels that sit inside the basket and displace grounds before you tamp. Not the end of the world and it has not seemed to have made any massive differences in my espresso. It absolutely functions as-is, but I do wish they reduced the lip so I didn't have to grind it down myself to use a better funnel. At the end of the day, you can pull great shots with it and the capacity claimed has been accurate (18-22g).

Nicely made filter basket, however the basket does not fit the Stilosa EC260BK - the ID is the same as the OE basket but the OD of the top flange is about 1.5mm wider. The basket gets hung up on the brew head of the EC260BK machine.

This is a perfectly made 51mm filter basket that has great dimensions and your tamper will not get stuck ! Fits perfectly doesn’t fall out when cleaning all the good things no complaints if your looking for a replacement of your current basket this is what you should go for I’ve purchase over 3 baskets (HUGH, Leverpresso, normacore,) all are just not right but this IMS precision is perfect

I just switched to this basket and it’s been life altering for my espresso. I purchased a bottomless portafilter and was using the included basket. After about a weeks use and 50 shots later, I was about to give up. My shots were sour and completely undrinkable. After switching to this basket, my shots are delicious. I can taste every nuanced note of my freshly roasted beans. And no more sourness or bitterness! I’m now enjoying every sip! My 51mm Iptake spring mini tamper fits perfectly in the basket!

This devices seems to be a very nice quality build but this is ruined by the tapering of the basket near the top that make it too snug for 51 mm tampers. The tamper actually moves nicely through the middle half but gets stuck at the top. This is bad in general because even if it were slightly larger and didn’t actually get stuck it still risks suctioning the puck out of the screen. Potentially fixable by hammering a correct diameter hard object into the top while the metal has been heated and then letting it cool with the pegged object left inside or a pipe stretcher. Consider increasing the aperture of the top of the basket so that it matches the mid section. If there’s a structural reason for the convex walls then consider slightly increasing the entire aperture. Tested using Ikape and Normcore 51 mm tampers on a 51 mm 3 cup basket.

Tried it on ECP 3630 and due to the faster flow rate design had to grind my coffee a bit finer. Fits around 19g of dark roast and 22g of light roast before touching the head. Please note that if used with cheap machines like mine, you definitely have to do pre-infusion for like 10s and wait ~5s for it to soak. Otherwise, you will get channeling because of lower flow restriction.
