i received the kingcamp cup, and the first thing I always do is hand wash everything. The reason I am giving it 4 stars verse 5 is because even tho I hand washed the cup the lettering easily peels off. That has been my only downfall. The locking lid is great. I poured in my iced coffee and turned it upside down and there was no leakage. I do plan on buying a few more, as this will be great to use when we do our camping trips.
