I have a Samona grinder from Peavey Mart.
What it taught me beside Never buy this grinder
Decide if it will live on your counter or do you need to tuck it away between uses. My grinder is too heavy to pop in and out of a cupboard.
How much noise are you comfortable generating? Mine is brutally loud.
Look for quality.The metal surrounding my grinder head lock down screw to lock it into the base started to degrade and loosen. Pain in the assets. Had to drill and tap it 180 degrees away to get it functional again.
Next grinder will be light,quiet, durable and have a dedicated or accessory foot switch
