About this item

At the heart of this machine is a dual boiler heating system. The boiler, for the espresso shot, is PID temperature controlled, while a separate steam boiler offers instant and powerful steam on demand. So you can extract your shot at the right temperature, delivering optimal flavor, while simultaneously steaming your milk. Shipped by our friends at Breville. This item only ships within the United States.

Failed quickly

Tiffany B. · 2025-10-13 · Verified purchase

I purchased this machine a couple months ago and the steam function has already completely stopped working. It's frustrating to have such an expensive item break so soon. I expected much better durability.

★★★★★

Worth the investment

Upgraded to this from a simpler machine and the difference is night and day. The control over temperature and the instant steam power truly elevate the coffee experience. It’s a joy to use every morning and produces excellent results.

Decent, but too large

Lauren M. · 2025-09-17 · Verified purchase

It makes good coffee, but it's very large and heavy on my counter.

★★★★☆

Solid machine

Good quality and brews great espresso, just wished it included a grinder.

Finally, real cafe drinks

Gabe Z. · 2025-12-13 · Verified purchase

I've been looking for a machine that could replicate cafe-quality drinks at home, and this is it. The separate boilers for espresso and steam are key. My lattes have never tasted better, and the rich espresso is consistent every time.
