Has anyone used buildet trend?

Hey everyone!

I've just started a new job with a construction company and they're exploring buildertrend software to see if its right for them.

I've used hubspot's free version for sales and lead tracking so I am familiar with the CRM part of things, but am not familiar with the project managment end of Buildertrend. There's no free version to test drive, just money back guarantee (and I don't know if 30 days or the reduced intro price for the first 60 days is enough to learn and explore it).

I went through a demo with a sales person but am interested to see/hear how it interfaces with quickbooks, and how user friendly it actually is for the guys in the field to use the mobile version.

Anyone out there use it before? It's tough to source comments that aren't paid or selected reviews.
