Professional essay writers - negative feedback?

Has anyone heard of this service and if so any negative feedback? I'm in the process of placing an order and thus far they have been pretty good i.e. not pushing for payment and even allowing a summary prior to purchase from writer on my particular subject !

I'm still a little reluctant as I've been burnt in the past from other companies. I usually use ukessay however Its uk based so double the cost in Australian dollars.

Any feedback would be great

thanks
