FieldGuide for A&A?

We are currently using CCH Prosystem FX and have been looking into cloud based solutions. We were somewhat impressed with Caseware and Inflo, but it seems like the reviews of both among firms that have switched are mixed.

Enter: FieldGuide. There was 1 firm that had gone with Inflo, but was so impressed with FieldGuide's demo, they told us they wish they would have gone with them. We also were given a demo of the product, and we are thoroughly impressed. Does anyone have any hands-on experience with FieldGuide for A&A?
