Soyabean, dun worry. I keep myself sane by saying, what I have done was done, there will be always seasonal discounts,etc, um tui also no use coz this is life man. hee, same goes with the additional ML, not mine means not mine...
Fennie, I can say jujube more durable, coz it has a bit of thermal effect. But hor, the closing 'magnet' thingy, if too near to metal, the bag may stick to the metal area (eg car, steel surface wall, etc), other than that, its quite good, comes with changing mat. It is slight heavier than lesportsac coz as mentioned, thermal effect materials are being used and it is double layer, as prevent split water in bag from flowing out.
