Not 3 days
I was excited to get this bundle based on the description and the reputation that RTIC has gained in my house. Wanting to know how well it worked, I grabbed a bag of ice and put it in the cooler and left it on the porch. Opened it once at 12 hours and once at 24 hours to check amount of ice melt. Weather outside was in the 50s-60s. At 12 hours half the ice was melted. At 24 hours it was all gone. I can't imagine how it would perform in warmer weather or with more frequent access to items inside. Super bummed.
