I think they work much better than other dry erase markers. Very Highly pigmented and they don't dry out when doing a lot of writing on the dry erase board.
I constantly have issues with these markers writing too lightly, even when they are brand new. I try to do what is suggested on your site and other sites to increase the effectiveness of the markers, but nothing seems to work. About one in five of these markers works well out of the box and I don't know what else to do to get the nice, even, dark colors that I once got from the more toxic dry-erase markers that once were prevalent.
