The cup appears to be of good quality in terms of appearance, texture, and overall look. The only thing that bothered me was the lid, which does not have a slot for a straw, so it is only suitable for hot beverages or water. Also, the flow of liquid from the lid is a bit "strange" as there is no specific point (hole) but rather openings all around, so the liquid will simply pour out from wherever you turn the cup. It seems like this could potentially be a problem, although I didn't experience it while using it. Other than that, it is a very nice and eco-friendly choice for those who want a cup for hot beverages.
