I need to drink a lot of water, on keto, and I don't like water. I bought these thinking, maybe it'll help. My straws arrived today. And I thought, "That's a stupid idea, a straw isn't going to help you drink more water!" Then I slurped down half my Artic cup (30 oz). So I guess I was right! LOL
No metallic taste, 2 cleaning brushes, 4 bent straws and 2 straight. And they're BPA free. Definitely a keeper! :-)
