This thing is awesome. However I don’t use it. I bought it at the end of last summer for $50. Used it once but was so busy with work I didn’t get to enjoy summer and use it like I had planned. So it’s in new condition. Super clean. Only had a couple bottled waters and 2 cans of beer in it for a day lol. It’s powered by your car dc port and works very well. Even if you only plug t in every few hours, it keeps contents ice cold. There are pouches on the outside also that stay cool because the inner wall isn’t made from same reflective material. If you travel or camp or take day trips or even just go to the park often, you’ll love this. Since I’ve only used it once I would like to sell it for $30, which is almost half price. Or you can buy one new for $50 or more in most places. I live in north wilsonville if anyone is interested in it.
