Just put the Silvia wand on my GC this morning, looks like I have yet another learning curve to master.
Re. pressurised basket the coffee gets forced out through the single hole in the basket and without that silly filter grommet it hits the portafilter spout under pressure and will spray sideways.
I found the Silvia wand MUCH easier and produce much better results without even trying.
