I bought this 80qt patio rolling cooler for my son for Christmas. I'm a 70-yr-old woman, and I put it together myself with ease. The only problem was that the screws that they provided to put the knobs on the top were not long enough. They only just met the top, and there was nothing sticking out to screw the knob onto. I went to the local hardware, and they provided me with the exact same screws, only longer, which worked perfectly.  There were no defects in this product, and I really like the quality and looks of it. I highly recommend it.
