My boyfriend and I love these cups! I've had it for about 3 weeks and I've used it 5 times already, that's how awesome it is. The cup fits perfectly in my car cupholder and is a nice size/shape to hold in the hand. The double walled insulation works very well. The cup doesn't sweat at all for cold drinks (great so it doesn't slip in the hand and drop) and it also keeps my hands from burning while having a hot drink (the outside of the cup feels just slightly warm). I can also confirm that the silicon stopper and the silicon rimmed lid do not leak at all! I've turned my cup upside down, shaken it many times, and it still has no leaks. Cup is also super easy to wash.
Aesthetically, the clear cup makes drinks look super pretty. And the metal straws are shiny and nice to look at too. I was at a bubble tea shop and someone even asked me where the cup was from since they thought it was the prettiest reusable bbt cup they've seen!
My only comment would be that the metal straws are a bit sharp on the angled side, and I noticed slight scratch marks on the inside of my cup from moving/swirling the straw. But honestly, this doesn't detract from my positive experiences with the cups - rather just something I noticed. It's possible that the sharper edge of the metal straw is even helpful if you're trying to puncture the plastic top lid of a throwaway bbt cup.
Overall, great purchase! I would buy more for my family and friends :)
