The ECM Technika IV Profi is an outstanding machine that is very well built and makes excellent java. However, to maximize its potential performance I would highly encourage upgrading your grinder from the Bodum Bistro to something with a bit more precision with regards to the coffee grind settings. The key to a making a good espresso great is always going to start with the grinder first and the ECM will deliver a more coffee shop caliber coffee when paired with a good grinder. I would suggest contacting our sales team to discuss some options that will work best for that machine and best for your particular needs too. I hope this is helpful.
