These guys know their way and already developed some nice plugins, so I am quite confident they will deliver.....but at the current stage most of the features are "in development" and their roadmap is not really clear or clever....if you check it's based on feedbacks, but there is no time-frame of the current features that should be shipped in the PRO by default.
The speed is great, backup is fast and so restore, but again, it's just too basic without the PRO "future" features that they have to deliver.
The deal terms are good enough especially with the new tiers, but so far for the same pricing there are more mature and robust solutions on LTD.
I hope they will spring, but some clarity should be made in the ETA for pro features.
