Good day! I was really excited about my personalized chilly's cup series 2..i love the texture and the color i chose plus the engraved name on it. it doesn't spill and no leakage on any sides. however, upon my first usage noticed how the temperature immediately dropped - way different from the 4 hours as said on advertisements. i less than 30 minutes, my suppossedly hot drink is already warm. ..disappointing though.. ..if only i could send it back for the company/management to check on the insulation/maybe any damages on my cup i would definitely do so just to make use of this purchase......
