I had a great experience buying this mug. As I had only a few days in the US, I wasn’t sure it would be deliver on time. So I sent an email and was really glad to not only be assured it would be delivered but also was treated with kindness and warmth. That made my decision to go for it, felt welcomed and certain that the Byta team cares and respects their clients. Also the product is absolutely great, got a lot of compliments since using it.

Byta all day

I use my byta’s every day all day. Favorite cups ever! Glad I can easily replace the lids whenever I break one or stain one too much to justify, ha! <3

Secure fit, questionable mouthpiece guard

The lid has an awesomely satisfying seal, but the sliding guard that covers the mouthpiece loosens too much after just a little use. When I tip the cup to drink, the guard slides down and covers the hole so no liquid can get through! Also a bit difficult to clean, which is how my first lid broke. I would take the guard off to reach the coffee stains underneath, then just pop it back on the lid... worked the first few times, but the little tabs on the underside of the guard gave out really quickly. It was a sad day.

Hot Stuff!

Keeps my tea hot and drinkable. But it does take some practice drinking from it to keep it from dribbling on you. Still, I love it!

let's just say....

Let's just say I love it enough to care when I accidentally forget it at a friends house & constantly pester them until it's back in my hands. which... guys... that's a lot for me. No but really, I'm very selective with every purchase I make. I love the cause. I love the thoughtfulness. I love the look. I love the performance. It's born out of a good brain & good heart. SUPPORT THIS. Three cheers, an amen, & a swipe right on this purchase!!!
