There are two types of water which ppl often mistaken.
1. Drinking water = white cap.
2. Mineral water = blue cap.

Anyway, the Sea Master drinking water current bottle design imo is stronger than others e.g. Uro, LaBoost, etc.
- take a new bottle, open the cap, turn it upside down 180° (pour it into water dispenser etc). the bottle will have a minimal shrink/deflate during pouring. Other bottles deflates more maybe due to thinner design.

Back then it was just RM6.50 per carton of 12 bottles, now iinm it's RM8.50

Imo, in terms of taste (and smell?): Sea Master > Uro > LaBoost.
Not sure abt mineral water though, I only buy drinking water, in cartons (12 bottles).
