As has been pointed out in the past, i give the sites are hard time when I do not think they are pulling their weight. But I am always willing to advertise good work as well.

Over the past 5 days my sales have increased by 500% on DT.

Yes!! same here, very good sales. I dont know why??? but DT somehow strikes me as a very stable, very secure agency, inspiring confidance. One of these places you can rely on, if you do your homework properly.

DT has passed IS for me this month.

Same for me, they are doing well for me despite more annoying credit card based refunds. I do wish that they would absorb these costs since our images have already been downloaded.

In last 5 days I had more sales on DT than in whole october.

I don't think I have ever complanied about DT.
Their sales are consistent and i like the site very much.

DT is one of the good guys among stock sites, IMO. Fair, efficient. The only thing I hate about DT is having to submit vectors one at a time. And the title length allowed is shorter than other sites. I love their stats page.

My sales there have been a little weak in Nov so far, but I had great Oct and Sept.
