I did a lot of research before purchasing Tier 3. I couldn't find a single negative point. I plan to use it for my custom art business to reach out to interior designers and architects. I haven't used it yet though, I'm giving it 5 tacos because of all the good stuff I found about the tool and its makers. It seems like a solid platform. The team has been in this business for a long time and it seems like they'll keep developing it.
