Does the job - but warps when hot
on 3 January 2014
This is a much better filter than the "creme perfetta" thing that comes with the machine (which like others has helped to redecorate my kitchen in a nice shade of espresso).
The only issue I have with it is that when it heats up the metal seems to expand or warp, and it pops out of the holder. I can usually press it down to hold it in place long enough to twist it into place, but it sometimes pops coffee grounds out unexpectedly. Not an awful problem but not ideal!
