Poor quality, Stay away. They say they have over 5481 PHD Experts, and I was expecting that my Data Analytics assignment would be completed by an Expert in Data Analytics, but I was wrong. The completed assignment contained just a list of definitions, most of them without any relevance to the topic, and the main discussion was actual a google search result of the Economic analysis of Walmart, instead of having a proper Data Analytics critical analysis of how Walmart is using Data Analytics.
Plus there were so many "google translate" expressions that had me scratching my head for trying to understand what the writer wanted to say here and there.
I have asked for a review which did not change much, it just added a short conclusion at the end, as I mentioned that it was missing anyway.
In conclusion, I wish I could say something better about them, but for now I would recommend you to stay away from these guys.
