Pros: 5 of the colors write well and those few are fine (until you try to get them off) and yes they are low odor.
Cons: majority of the colors are so watered down that when you write with them the ink bleeds together and nothing is legible. The orange and red cap pens write in the exact same red color as do the light and mid blue capped pens. The yellow, light green, and pink are so light and watery that they're nearly invisible. Worste con of them all is they stained my whiteboard, leave very bad staining when erasing.
