I just can't deny anymore that the IceFlow is superior. She's leakproof. She's got a handle at the top for easy carrying.
My cup still performs great and looks brand new, the straw included. It's been my primary water bottle since 2022...
I have a 30oz and mine only keeps ice for about 8 hours. Its a bummer cause I would love to have ice the next day...
They are almost impossible to clean 100% as the lid doesn't come fully apart.
