I take this tamper-form to stop the Motta-tamper, and as a base for pressing the coffee in the portafilter. This works very well with this silicone mold. Despite the initially very high pressure with which I had pressed (I'm still learning :-) has taken no damage to the form. Every now and then I dab it dry, if a few drops were still hanging on the filter holder, but otherwise it is very easy to maintain. Who wants to stand up no big Tamping Station, is well served with this silicone mold.
