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 Damian Toupal

the thing works great! It came mostly charged but I fully charged it before use and it only lasted about 10 minutes. It's nice that this is USB-C charging, so it's a guarantee for the future, at least for now. There is a small cover for the charging port which makes it nice because I will be using this outlet and it prevents dust from entering. In terms of use, I just ground up a few Starbucks beans for use in a French Press and it only took about 5 seconds to grind the beans and they came out perfect. I did too much so I decided to see how long it would take to grind the rest before I grind the espresso and it only took about 3 seconds. This device shuts itself off after 20 seconds of continuous looping, but I don't see how anyone could ever use it for that long. So far I'm very impressed. Pros: Very fast charging. Portable and wireless. No need to change batteries USB C charging Grinds beans quickly and evenly Compact and easy to clean Cons: None yet
