What actually matters

Set up as a medial bell-class unit, it does the job without asking you to improvise.

In practice

• Care: a rinse and dry cycle in the usual rhythm keeps it looking fresh.
• First use: no break-in ritual required beyond a quick wipe and a glance at the label.
• Storage: stows neatly, taking no more room than a loaf tin when out of service.

Reasonable to buy, easy to live with, boring in exactly the right way.
