Need to be more careful with cleaning!
I was originally concerned about the impact of stainless steel on taste and the potential substances released when in contact with tea or coffee, which is why I chose the Cuppe. Since we bought this water bottle, my partner uses it almost every day to take coffee to work, and he loves it.
There haven’t been any major issues; the seal is excellent and it's easy to clean(if you have dish washer). The only problem we've encountered is that using a common green sponge caused some scratches on the lid and the body. People who are particular about this might want to be cautious. Since then, I've been hand washing the cup to avoid further damage. Also, coffee can stain the white parts of the lid, but I believe it can be cleaned and isn’t a major concern.
The capacity of this cup is just right, and I’m really glad I purchased it. My partner's colleagues also love it, and we would happily recommend it to more friends!
