Review on Convenient Cordless Coffee Grinder Electric: DmofwHi USB Rechargeable with Stainless Steel Blade and Removable Bowl - Perfect for Grinding Coffee Beans, Spices, and Seeds by Colin Watkins

I am very disappointed, the battery only lasts for 1-2 grinds for six to eight cups of coffee. Also, you have to disable it to use it. So every time I use it I have to unplug it and plug it back in after use, otherwise I'll have a dead battery and unground coffee beans the next morning. Not cool, I know this will wear out the USBC connector either in the grinder or in the cable itself. Funny how you have to unplug and plug it in every day. The three easy-to-clean issues, etc., above are silly issues. They make it impossible to properly rate this product. Topics should be battery life, ease of use, processing quality. On the plus side, it makes great coffee. I am thankful for that every morning. :-)
