Verdict
De'Longhi EM450.M is interesting and very similar to its Dedica sibling, with a useful pressure gauge and a large water tank.

Third-party reviews

What customers like about De'Longhi EM450.M

  • The 15 bar pump gives the pressure a proper espresso needs.
  • The cappuccino program keeps milky drinks simple.
  • The automatic milk frother does the foaming for you.
  • A pressure gauge lets you see what the pump is doing.
  • It takes ESE pods as well as powdered coffee.
  • The 1.7 L water tank is large, so you refill it less often.

What customers don't like about De'Longhi EM450.M

  • The steam nozzle can pop off unless you secure it with a zip tie.
  • Milk from the steam wand comes out bubbly rather than creamy.
  • Switching from steam back to espresso takes a long wait.
  • The steam parts are plastic, so the build feels less sturdy.
  • There is no built-in grinder, so the coffee must be ground beforehand.

Verdict

Espresso fans who want a proper cappuccino most mornings will find the De'Longhi EM450.M a sensible mid-range pick, with a 15 bar pump and a 1.7 L water tank. Its cappuccino program and automatic milk frother take much of the fuss out of a milky drink. A pressure gauge lets you check the shot, and it takes ESE pods as well as powdered coffee. The steam wand can texture milk for a latte macchiato, though the foam comes out bubbly rather than silky, and the steam nozzle can work loose unless you fix it with a zip tie. The espresso tastes balanced, not bitter or sour. It suits a home or office buyer who wants good espresso and milk drinks, and does not mind a little fiddling with the milk.
