Disclaimer: I've only been using this product for 24 hours. so some of you might think it is ridiculous to give it 5 tacos when I have hardly had a chance to test it. So here's why:
1. Ease of use - so far 10/10
I was up and running within minutes. I have no tech background.
2. Clean interface - it's simple and logical and the functions work.
3. It's useful for organising connections - 10/10
Within minutes I had sorted some of my connections and added labels. In the past, I have used products like Octopus and Linked Booster but this is a far superior product. I can finally manage connections.
4. Clean clear inbox function -10/10 I can see what messages I have sent and easily track them. It's like Gmail only better.
5. Pipeline manager - I set up a pipeline within minutes - this only gets 6/10 because nothing seemed to happen for a long time. I originally set it up to do a profile view followed by a message. This didn't seem to work well. So I skipped the profile view and went to sending a message instead. This task was performed easily.

I have only got tier one but am thinking of upgrading.
