Well unfortunately it wasn't. We purchased the lifetime 77 model. We packed it with cold food and drinks filled it full with 40 lbs of ice, and headed out for 4 days of camping. Not knowing how it would perform, I made sure to keep it sitting in the shade. Unfortunately within 48 hours the cooler was already about 60% water. By the end of the third day it was 90% water. I do like the storage capacity, I just really wished it performed better. Love its american made, but unfortunately im forced to return it. I cant have that amount of money tied up in a cooler that doesn't work as described.
