1. It’s incredibly convenient to flip up the spout and drink and then flip it back down when done. It definitely beats screwing on and off a cap as many bottles require to be done in order to drink from them.
2. It fits a wide variety of bottles that have a neck of this diameter.
3. It is very easy to keep clean.
4. It’s constructed of quality materials including the straw which is of a nice thickness.
5. The handle integrated into it is very functional. I can use it to carry the bottle or to attach the bottle to a bag or strap.
6. It’s BPA free.
Cons: There aren’t any to discuss.
