Overall its a very good product for everyday use and commute. Too heavy for travel -Prefer to use my nespresso travel mug for on the go drinking and espro P0 for insulation.
Pros -
1. Looks great. Sleek design. Awesome colour options available. Modules are replaceable.
2. Both cup and bottle are double walled and insulating. Keeps water cold for a long period.
3. Bottle is leak-proof.
Cons
1. Very expensive compared to other bottles on the market.
2. NOT dishwasher safe.
3. Heavy.
4. Stainless steel part heats up when in the sun - glad i went with a coloured cup.
5. Steel base gets dinged, dented and scratched.
