I am able to use my password vault across all my devices and feel safe about it. I like their Firefox and Chrome extensions as well as the Yubikey support (and NFC Yubikey on Android). All of their software is open source and freely available (as should be the case for anything you'd trust for security matters).
In addition to being pleased with the software, I've also been happy with the support: When I initially signed up I had a question and submitted a support request on a Sunday morning and got a response back within an hour. Nice to see that level of responsiveness, even when I wasn't a paying customer yet.
What do you dislike?
In the webapp there are offerings for organizations and personal and business and it took me a bit to figure out what that all means.

Keep up the good work!
What business problems are you solving with the product? What benefits have you realized?
I needed to securely store all of my passwords and access them from any device. This software /service does exactly that. Also, since it's all OSS, I know I won't run into any trouble far into the future in the case of getting bought up or anything like that (see Lastpass/LogMeIn).
