Overview
Banana Bros builds this black aluminum grinder to mill dry herbs and spices at the press of a button. It recharges over USB, so it works at home, on a picnic or at a campsite without a cord.
Automatic grinding and a metal body take the wrist work out of spice prep. The limits are an unlisted battery life and capacity, and the lack of dishwasher cleaning.
Who it's for
Home cooks, picnickers and campers grinding dry herbs and spices on the go. Heavy daily milling of large quantities calls for a larger grinder.
Pros and cons
- Not dishwasher safe
- Battery life not listed
- Capacity not listed
- No carrying case
Performance notes
A motor spins the grinding mechanism automatically, so the result depends on how dry the herbs are and how long it runs. Battery charge sets how many sessions it lasts. Cleaning by hand protects the electronics.
