Bemega | Mens Titanium Insulated Cup

As an experienced mechanical engineer, I have a few observations about this cup. Firstly, the surface of the cup feels a bit rough, indicating that the base coat might not have been applied well. It doesn't look very high-quality, so I wouldn't recommend it as a gift. Secondly, looking from the inside out, there might be an issue with the titanium alloy processing, which also appears to be of lower quality. The rim is not particularly pleasant to use; I was thinking of keeping it for collection purposes rather than using it. Lastly, the lid has some impurities and bumps that don't smooth out. However, I appreciate that the seller offered to send me a replacement, which is a nice touch. Overall, while there are some flaws, I see potential for improvement.

Sure, I'll definitely come back to buy again next time.
