Convenient, good response speed when searching. But the problem is accuracy. I've logged in with my account, the company I'm working for have purchased your service. However a lot of results are not included in the premium access, therefore next day, with really high possibility, I'll find that I can't download almost every links I had sent last night. It's totally waste of time. A premium access setting or filter will be reqired at least.
