I wish I could add a screenshot to this review, but anyway if you go to https://www.leadrocks.io/#Pricing you will see for yourself that all plans SUPPOSEDLY include "unlimited users"...but by having a live chat with their customer service, I was informed that in fact this was NOT implemented yet and would be implemented next year...
It's not very good practice to list something as included in all your plans when it's not even implemented!!:(

As another Sumo-ling noted, LeadRocks' customer support also claims that the email address on the Leadrocks account can not be updated. That is another bummer.

I bought this product mostly for my SDR/teammate. The only ""solution"" given by LeadRocks was to ask for a refund and then buy another deal with my teammate's email address instead of mine. Besides this being impractical, imagine also if later we want to switch to another teammate using LeadRocks...ladies and gentlemen, that would be impossible as the LeadRocks account would stay permanently tied to the initial email address...

(of course until hopefully eventually they implement the advertised feature).

So beware of this. Other than that, we can not judge yet the quality of the data.
