Overall I'm very happy with my purchase and have begun using this on a daily basis.

PROS:
- Easy setup. I had a functioning chatbot up and running in 5 minutes.
- Returns perfect answers 99% of the time
- Answer fast
- Clean, simple UI
- Tier 3 offers phenomenal value with easy branding & domain controls

CONS:
- It can only read from the 1 default tab in a connected Google Sheet. If you have multiple tabs, you need to upload them separately to add to the knowledgebase
- Sometimes it didn't return complete answers (Example: My data set has over 1K rows. I asked a question and it should have returned data from 5 rows but it only returned 3)

Despite the minor drawbacks, Botsheets is a keeper for me and perfect for my use case.

5 TACOS! Thanks app sumo and Botsheets team!
