The most important thing is that it provides real time scraping of websites, which makes us save lots of our precious resources by not waiting until we get all data from server side or manually as in other tools available out there today.
It has some limitations like sometimes when you are trying to scrape multiple pages at once then its can be slow but still i think this tool does provide good quality results with ease. I would recommend anyone who wants an easy way to collect large amount of web content without any hassle should use scrapup up services because they have very friendly support team too! We used them during my last project where we needed lot's of information about different companies so after using their service now am able to gather info easily within few minutes instead of hours required before while gathering same kind of stuff through manual process.
