I bought this obviously because it’s adorable! I wasn’t really expecting it to function for very long (I live in Arizona & even the best coolers can’t keep up with the heat), but we took it for a night out with friends (around 5pm- still 100 degrees out) & the next day late afternoon I went to empty it & there was still ice! Granted a lot of it was melted, but some was still in small cubes!! Very impressed with this cute & functional cooler- nice job Igloo :)
