I came to the conclusion that almost ALL writing services are scam!
I purchased my first paper from S2paper, i read some good review about them thinking they should be ok, well, the work was ok, i certainly wouldnt say great as i only had a pass, and they delivered later than the time they promised which is certainly very typical now that i read a lot of other comments from this site but it was ok too as i didnt order it at the last minute.
The paper seen to be written from a journalist for the newspaper or some sort, (certainly not the academic level) as the writer used one reference for 2 pages writiting, it looked like a report rather than a research paper! and i end up had to spend hours to add more reference and alter the grammar to make it 'real', but it was ok too as i was in the hospital at that time so i was in desperation on that paper so adding a few more reference was definitely better than having to research for the whole paper but what really upset me was, i asked and paid for 3500 words 'excluding' reference but guess what, i had received 3300 words 'including' reference. When i confronted them, they simply told me they understand most universities will accept 3500 words+/- 10% so simply told me to 'suck' it! and the email reply was not very polite too!
If you want to consider this company, well, unless-- you are not in a hurry , you have patience and time to change the 'tone' of the paper and you dont mind them writinng less than you pay for, then sure, otherwise, i will stay away from it. They have been very dishonest about their 'product' and taking advantages mainly from students who might be in need with the writing services.
