If, like me, your requirements from a grinder are for it to be highly adjustable, durable, cleverly designed and robust, you can't go far wrong with
these from IKEA.
Apart from being practically perfect in almost every way*, they don't make a mess of your kitchen cupboards, having been cleverly designed to sit 'upside down' rather than in the normal fashion.
Nothing else I've used has come close to matching them. And I do a fair bit of cooking in other peoples kitchens and have come across some absolute tat in my time - most recently
these and
these.
And a special mention goes out to every single battery-powered grinder I've ever had the displeasure of using. Hateful bloody things.
*apart from only being sold in IKEA, which might be a problem.
