Review on 🌶️ Electric Salt and Pepper Grinder Set - Battery Operated One Handed Mill with Ceramic Grinders, Adjustable Coarseness, Funnel and Bottom Cap - Includes Lights for Easy Use - Perfect for Home Kitchen by Sarah Brown

These coffee grinders work quite well. Your power will be reduced in favor of the motor and battery area. It's okay, you just have to refill them more often. The included funnel is almost useless. You might as well fill it with a spoon. Perhaps the flexible funnel could have another use. I wish they were rechargeable but didn't want to pay extra money for them. So far they're working great. I hope it lasts longer than other motorized models I've seen. So far, so good.
