I wasn't going to leave a review, but this morning I dropped the cup on my porch where it rolled and dropped onto the sidewalk. Still, NO SPILL. Only a few droplets on the lid, not even the straw leaked. The cup also doesn't look damaged. I now appreciate the screw on cap design! I haven't really tried ice in my cup since I don't really use it, but cold water and cold brew stay cold a long time. Worth the buy!
