If you are on a long car ride this is a must have. The Switch is good, maybe 3 or 4 hours of continuous use and then it needs to be recharged. Bless yourself with lasting quiet bliss that comes from the back seat and make sure you get one of these for your angelic heaven born children. You will regret you didn't once their batteries die and these angels turn into demons and doomsday erupts out of your back seat spewing anger and hatred that can only be described in apocalyptic nature. As soon as Pandora's box of unrest opens. Spring. good luck my friend. Much luck.
