Overall I would say they are very good for their price. I bought these because long sleeve necklines always choke me, so the 1/4 zip is a good alternative. They are great for my purpose of being too cold for a basic t-shirt but too hot for a light jacket. The thin material offers little additional warmth. The only problem I've encountered is loose thread. Pros: light weight, nice colors, very cheap (usually one is $10 and three are $30). He has no tag. Because it's so thin, it can be packed in my suitcase without taking up much space. The size fits perfectly. Cons: All have threads sticking out before they're even tightened. They are very thin so if you want them to be warm you will be disappointed.
