Review: So far so good, works well with, and fits my Casabrews CM5418. The increased number of holes compared to my previous bottomless portafilter requires a finer grind to maintain proper espresso pull. I don't get channelling or leaking with this portafilter, which was the main reason for buying. Quality seems good.
Review: Bought this after researching to replace the pressurized portafilter setup that comes stock with the Mr. Coffee Cafe Barista. This basket (3-tab, 4 mm prongs) fit perfectly, and allows me to take better advantage of my upgraded grinding equipment. It also greatly simplifies cleaning and opportunities for rancid coffee to build up in the pressurized portafilter and basket setup, by reducing the number of parts to be dismantled and cleaned down from something like 10 to 2. The portafilter includes a spring ring that holds the basket in place, simplifying puck knock out and keeping things together. The parts seem very well made, and I like the naked portafilter setup, which helps me get a better understanding of how well I ground, distributed, and tamped my beans. I also appreciate the added depth of the non-pressurized basket, which allowed me to get my dosing up from approximately 12 g (if I tried REALLY hard) with the pressurized basket, to up above 14 g. Still experimenting there, but there's loads of room to go, and you can pull a much larger shot with this setup. The final quality of the espresso, to me, is greatly improved with this non-pressurized setup, but only because I have a very good grinder and an existing setup used on a manual espresso machine. You'll also have to go to a custom espresso pump duration, because neither single nor double will be equivalent to what you'll end up with once you change the required pressure and volume of beans in your basket. If you intend to switch to the non-pressurized setup, be aware that this takes out much of the forgiveness that comes with the out-of-the-box pressurized setup, meaning your mileage may vary. But if you have a grinder capable of espresso grind, and a tamper (51 mm works for me), a dosing funnel, and maybe a distribution tool, you're much better off turning your semi-automatic into a mostly-manual machine. But if you want to make the switch, this portafilter and basket is a perfect upgrade to your setup, for those with the Mr. Coffee Cafe Barista machine and possibly others.
