Coolest is another product revamped and upgraded to the extreme! This is the cooler we have all been waiting for, with built in led lights for the inside, the party doesn't have to stop when it gets dark! Bigger wheels give it more versatility and let it roll on many different surfaces. A built in blender makes it a must have at any barbecue or day at the beach, blend your own drinks and no need to plug it in with the built in battery that can charge your mobile devices as well. If you decide to back them, please leave a comment on their campaigns comment page that you found their project through IamABacker.com , Thank you.
