VAlinks Coffee Mug Warmer, Self Heating Coffee Mug & Self Stirring Coffee Mug, Rechargeable Electric Mixing Cup with Lid, Temperature Control Heated Coffee Cup Keep Coffee Milk 131℉/55℃

I believe this unit is a bit over complicated for what it is - I think it should simply function as on or off.Too many settings to cycle through with only one control button.🤷🏼‍♂️

I drank my tea too fast to tell if this keeps it warm, so I can't speak on that aspect of this product, but the rest of it is really neat. You can set it to stir every 30 seconds to prevent settling. It's easy to charge and wash. I felt like it kept my drink warmer than a regular mug does, but that may also be because of the insulation. I wish this was available in more colors!My biggest gripe is that the drinking hole is... odd. It's raised and a noticeable distance away from the edge of the lid, so it's very awkward to drink from.

I wanted to give this a higher review but I've stopped using it because I'm scared I might swallow the stirrer which is basically just a small magnet attached to the bottom of the middle of the cup. I'm sure it has been thoroughly tested but I can't seem to get that out of my mind, my wife also thought the same.I do appreciate the ability to keep my drinks warm, but don't forget to put the lid on fully or you are going to have a big mess on your hand
