Third-party reviews

What customers like about Ninja ES351EU

  • 60 grind settings let you fine-tune each cup.
  • A 250 g bean container means fewer refills.
  • The automatic milk frother makes cappuccino and latte without a jug.
  • A separate milk container holds the milk for frothing.
  • Adjustable coffee temperature lets you pick how hot the drink is.
  • The two-cup function brews two drinks in one go.

What customers don't like about Ninja ES351EU

  • Automatic milk circuit cleaning is missing, so the milk side needs more care.
  • There is no water filter, so the descaling program does more of the work.
  • The milk temperature cannot be adjusted.
  • There is no latte macchiato or iced coffee program.
  • There is no automatic tamper, so tamping stays a manual job.

Verdict

Anyone who wants to tune each cup will like the Ninja ES351EU. It grinds beans with 60 grind settings, so coarse or fine is easy to dial in, and the bean container holds 250 g. The automatic milk frother and the separate milk container make cappuccino and latte with little effort. You can also set the coffee temperature. A portafilter and a steam wand let you work by hand. It takes ground coffee as well as beans, and the two-cup function makes two drinks in one go. The downside is the milk side. Automatic milk circuit cleaning is missing, and there is no water filter. It suits someone who likes to experiment with beans, milk and temperature and does not mind a bit of cleaning.
