After testing the resistors I found that they are consistently 630 ohms, not 1k ohm. The fact that they're so cheap means I'm not that upset, and if you put two in series you get 1260 ohms, which is about 1000 ohms if your circuit isn't too specific. However, I am disappointed with the quality. I haven't tested the 1/2W resistor claims just because my wattage isn't high enough to hit that limit, but since the resistor labeling is erroneous I would be wary of their wattage. I've seen some mentions of them not being suitable for breadboards due to wire gauge, but mine seems to work well enough on breadboards I own.
