I may not be using the tool to the fullest, because my needs are quite specific and I don't need thousands of contacts, I need few hundred key people from USA. Looking for them on LinkedIn then using cleanlist Edge extension to get email and mobile number is terrific. It feels like cheating, being able to get direct cell numbers of key people in big companies. :)
I have upgraded from Tier 2 to Tier 5 after using this tool for a week. Hope it gets only better from here, even if LTD's would not get any new features, it still feels like good value.
