Got the coaster because why not right. Really pairs well with Badgers cup. The rechargeable battery was a nice feature too. For those of you wondering how it works there's a switch on the bottom that gets pushed in by weight like a cup. Just don't try it out on a soft surface like a mouse pad like I did

Very nice that the coaster has battery and cable options as well as the drink and cup is fire

Fill up any supp cup with water and turn it into a multicolored lantern to party alone in my room

For me at least, it isnt wobbly and the colors that it shines works really well with the pixel cup shaker i got

While the LED lights can't get past certain flavors like Lean, it's still a great visual complement to Badger's shaker cup. It lights up just enough that I can see it out of the corner of my eye and remember it's there, but not to the point of annoyance.

As a bonus, it matches the rainbow lights of my desktop's keyboard and PC, too!
