Glad that i manage to do a one-to-one exchange for my mum's tupperware.
Wanted to know how fast they work & thus sent 2 containers which my mum has threw the lids away due to rat bite (very long time ago when we stayed in Geylang shop houses). Anyway, rat bites are not covered under warranty.
Those old yellow colour containers which i believe some of you might know which model i'm talking about. Anyway, they are replacing then with their one-touch collection. but due to no lid return to them, they won't replace the lid for me, free. But i just have to top up a $5 & a $4 (2 containers) & i'll get back 2 brand new one-touch containers.
Worth it? i feel that it's def. worth it.
just sharing my personal experience.
