Perfect Christmas Cup

I love all of my byta cups. This cup is the perfect Christmas gift, and fits in my hand so well! Hot Chocolate ready!

Love it!

Great! Perfect size. Love the color & texture. Never been a fan of the lids on these things, but I like the new design

Absolutely love

I love this cup. I purchased on a whim after looking at it for months. I love the color especially and the fact that it keeps my coffee warm. I do wish the 20oz came in the same color...hint hint. Also the 16oz is smaller than expected but still perfect for my daily morning caffeine fix.

Best cup ever

I now have 6 Byta cups and use every one. Have not found a better product for my coffee and tea drinking!

Still need to improve the lid

Beautiful color and I love the style. I usually use it without the lid as the lid is terrible and needs improvement. Difficult to drink out of lid as not enough liquid comes out and leaky. I really wish they would improve the lid especially given the price.... but then again I already reviewed one of these and went ahead and bought it in another color knowing the lid is inadequate. I don’t mind removing the lid when drinking out of it at work.
