Pro Very easy to use

The mouthpiece has rounded edges and is just wide enough to make it easy to drink from it without huge gulps or suction sounds. The ergonomic shape of the bottle along with the grip makes it easy to lift up and carry.

Pro Does not leak
There is a silicone pad on the inside of the lid just over the mouthpiece, which seals it securely when you close the lid. It fits very snugly over the opening and does not leak even when held upside-down, or on its side. However, you do have to remember to close the lid for it to work.
Pro Easy to clean
The straightforward design of the lid makes it very easy to clean both the bottle and the lid by hand, or in the dishwasher. Some water bottles have an intricate mechanism for drinking, with a lot of small, hard to reach spots, but the Thermos Intak keeps it simple.
Pro Helps increase your daily water intake
This bottle has a rotating meter on the lid to help keep track of how many bottles you've emptied, and also an indicator of how much water is left in the bottle. This helps some people drink more water, as it can give a sense of achievement.
Cons
Con Lid will need to be replaced after a while
The bottle itself is made from impact-resistant material, and will survive most falls. However, the lid itself is the weakest point in the whole design in terms of durability, so you will have to buy replacement lids sooner or later.
Con Lid can hit you on the nose
You need to hold the lid when you're tilting the bottle to take a sip, otherwise it might hit you on the nose.
Con The surface gets 'sweaty'
Since this is not an insulated bottle, condensation will make the surface of the bottle drip with water, especially if cold liquid is poured in on a hot day. This can make it a little harder to grip, and can also increase the chance of dropping the bottle.
