The lack of a retaining ridge allows the use of a 58mm hand tamp and the the pattern and hole aperture of the basket proves to be beneficial to espresso preparation.

Not only does it leave a distinct sunburst pattern, the inside bottom of the baskets receive a final cleaning using a laser to remove any jagged edges from the perforation process. The result is that every hole in the basket is clear of metal debris and the holes are of even size and shape, allowing for a more even distribution of water through the extraction.
