It's better to go play the money you would spend on this product in the lottery. Maybe you'll win something. This fridge does nothing. Stay away from this

With a cooler bag, it does a good job if you put cold water you have cool water throughout the trip for several hours in the car

Given the price, I would consider it good. Don't expect it to freeze an already hot product, what this specific cooler does is keep an already frozen product cool. If you want to keep it cold, I would suggest using an ice pack along with it. Due to its size, one can even carry it on the passenger's feet
