Great for those who have hand or wrist problems :)
Doesn't seem very environmentally friendly using batteries when it so simple to manually twist.
I am happy with these.with no button to press as gravity switched. few quid more though https://www.amazon.co.uk/gp/product/B07Z4R11TX/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
Strange. Mine have worked flawlessly for years and are the best battery mills I've used. When you're cooking they are ideal as you can stir with one hand and season with the other. Would never go back to manual.
