I purchased a full stack and I am very excited about the product!

Pros:
1) generous limits (100K records for full stack)
2) very responsive support team
3) simple interface
4) relatively easy to understand

Could be improved:
1) There is still some manual work to be done.
2) The dashboard could include more charts
3) I would love to see more use case videos

This is a 4.9 tacos for me and I think you should buy this as it has fantastic potential.
