Terrible! I think they are a scam. I ordered a paper because I took too many subjects and there is an assignment that I am not interested and I don't want to deal with it.
I picked top-rated writer and the writer don't even know the basic premise of academic writing, even after revision.
I barely got 20% refund because apparently the top-rated writer feature is non refundable.
I ended up spending more time dealing with this than if I have done it myself.
