I was excited by a metal spring, when the unscrewing and cleaning the machine slightly (about 3 mm) pushes the coffee sieve upwards, so you can easily see the screen without "headstand" the digester. As with all stainless steel surfaces is needed, however, every now and then a stainless steel cleaner to remove fingerprints from the surface. The outside of the unit seems also to be easily thermally insulated, so that you hardly can burn on the hot device itself.
