Do not buy YETI. Over expensive and too bulky for what they are. Also, their top screws on the inner part of the bottle, which just creates thousands of microplastics in your beverage.
Look for a water bottle that screws on the outside of bottle. So, whenever you screw/unscrew, the microplastics are not falling in your beverage.
I have a YETI and it is one of my worst purchases ever. Fuck YETI. Overexpensive BS.

I haven't tested them yet. Maybe it would be nice if some other people saved them, to safeguard them.
EDIT: I tested them on KOReader. They work. Yay.
I am still looking for a good dictionary PT-PT. If anyone knows of anything, let me know, please.
