Electric Mixing Mug with Auto Stirring - 15.5oz Insulated Coffee Thermos for Hot Beverages | Perfect for Coffee, Tea, Milk & Cocoa at Home, Office or Travel (Pink)

I got this on December 7th. I mix a lot of supplement drinks. I cleaned this as soon as I got it and started using it without charging. I have yet to charge it out of the box a month later! It’s very powerful and even mixes a big scoop of protein (hydrolyzed so it does blend better than other proteins I’m sure) but still if you are in the market for something like this just get this one. Again, so powerful and the battery life is astonishing. I use this multiple times a day and I’m just waiting to see how long it can really last before I need to charge it. I don’t ever leave reviews but I felt inclined after how impressed I was. My wife is jealous of my cup so I need to get her one now too. I just rinse it right after I finish drinking what I mixed and once a week rinse it with a little soap. BUY IT.Still haven’t charged it once haha. Love it
