Got it as a gift for my boss (we work at a design firm called DayCloud Studios) and it was exactly what I was hoping for. The only improvement I could make would be if there was an option to remove the battery pack when using the USB cord (it's a little clunky). But those are really minor things, and overall it's a great product for the price.
$30 for a neon look-alike is an amazing value, and everyone in our office is obsessed! 10/10, would absolutely recommend.
NOTE: If you plan on plugging it into the wall, you'll need to provide your own USB charging block to plug the cable into (standard iPhone charger cube, etc.), as one is not included. Not a big deal, but it was a small surprise that you can't plug it into a wall socket straight out of the box.
