Anyone using Draft2Digital to publish their ebooks across multiple marketplaces?

Just preparing my first book to publish with them. 52k words so far.

What attracted me to them was no cash upfront, a 10% share of any sales, and free ISBN included.

I was wondering what other community members have successfully published with them if you have found it a good company to work with and a model to follow, and what other tips you might have.

Cheers

D2D is good, I get almost as many sales as on Amazon. You also don't have to worry about getting randomly banned by Amazon when using D2D
