How do I recharge the mills?

The mills charge via a USB cable rather than disposable batteries. A full charge typically covers weeks of normal home use, less if you grind daily for large meals.

Can I use them for spices other than pepper and salt?

The pair is intended for pepper and salt, and the salt mill has a corrosion-resistant mechanism. Coarse spices like cumin or coriander seed also grind well; soft or oily spices can clog the mechanism.

How fine can the grind go?

The adjustment dial turns gradually from a fine dust for finishing dishes to a coarse crack for steaks and marinades. Turn the dial while the mill runs to feel the change.

Are they dishwasher safe?

No. Wipe the aluminum bodies with a damp cloth and empty the salt hopper periodically to prevent corrosion. The grinding mechanism should never be washed.

How does this compare with Peugeot's manual mills?

You get the same steel grinding mechanism and grind adjustment, plus one-handed electric operation. The trade-offs are weight, motor noise and the need to recharge.
