Hi, I have bought three thermosteel milton flasks for my daughter's school, my husband's office use and mine too and travelling etc. For some time my duaghter's bottle was keeping cold water cold but now its not at all keeping it cold for even 2hrs. Now when i used my other two flasks they are also not keeping the same. even they are not keeping hot water for minimum 2-3 hours. I have bought one around one year back and another two for about 8 months back.
I bought these after getting reviews from relatives and now i dont know what to do as these products are high in price and my got wasted i think.

please help.
