The service worked well up to the point they decided to allow it only to work on one device. That said, the extension and app often had issues. If the extension couldn't detect a network connection, the only way for it to connect would be to restart my browser, while I'm sure the trust token is also there for a reason, the option to allow it to 'time out' rather than logout would be useful, without having to go through fully re-aunthenticating. Unfortunately these changes are the reason I've now left LastPass and gone to another service.
