Excellent stuff! Tested leakage, with cold & hot water - Passed with flying colors! I hope this one will not rust or oxidise on the inside of the flask like the previous one I bought from Amazon. Prolly I need to wash it thoroughly if I used it on acidic liquid like lemon water.

First day using it only had one rust dot. Second day manage to get three and continue to spread. None of the stainless steel bottle I got have this issue. All water have been filtered as well.
