Easy to open/close lid and lid stays in place while drinking. Fits easily in a cup holder. Only annoyance is that the seal on the mouthpiece is a different material than my store-bought one - more see-through and a bit stiffer.

The cap is easy to open with just a button press and the lock holds up well and is mostly childproof. It has a handy dial to track how many times you've filled it.

This is the 3rd one i've purchased. It works as intended. This is a good bottle if you want something that works and if you are not the sort to find fault in basic things like a water bottle.

It is very difficult to remove the o ring gasket as required per cleaning instructions. don't bother. It’s now at the local dump.

The latch easily breaks/pops out when you drop the water bottle. Thermos brand but not insulated and the outside of the bottle keeps condensation on it so my hands stay wet. Looks like i’m going back to reusable, easily cleanable gatorade bottles.

The locking mechanism employs what looks to be a piece of acrylic. This means that if your bottle falls the acrylic will fail, and the bottle will no longer stay closed. The metal latch breaks easy when you drop your water bottle.
