“The bottle itself is beautiful but in terms of functionality, the design is severely lacking. I will never understand why companies don't just make the mouth of the water bottle *slightly* larger in diameter so standard ice cubes can be put inside...especially when Waterdrop is very clear about their products being used with *cold* water. I can get probably 50% of my ice cubes to fit (since the size varies of each ice cube in general) but even those, I have to jam in by hitting them with my fist. It's a huge pain and will eventually be the reason I get sick of fussing with it and stop using this bottle. Also, it sweats a lot and I think the glass is so pretty that I don't want to cover it up with the insulated koozie that came with it. It also doesn't keep your drink cold for very long and with all the Yeti/Arctic/Simple Modern-type products that keep your drinks cold for hours upon hours these days, it's just another reason this is inferior.”
