The American one is not very easy to use
It still has the shortcomings of ordinary plastic products, such as: it is easy to absorb taste. I used it to hold Chinese medicine once, and it took me a long time to drink water. It also smells like Chinese medicine, and I never dare to take it again. Also, the oil is not easy to wash off. I used it to fill bone broth once and it was very difficult to wash off, especially the lid.
I personally feel that the price/performance ratio is not very good, it is not worth it
