The support is great - I've never had to wait more than an hour for any issue resolved by their team! Their customer service has always been excellent too (even when it's not!). There are so many different features that you can use within this product which makes life easier in general as well. We have used other products like Dattco but nothing comes close to how easy they make things with altoNano. If there was anything we didn't love about them then i don't think its something specific enough or important enough to complain about. As said above though; Support timeframes etc could be improved upon - no complaints here either however these two issues aren't really worth mentioning since everything else works perfectly fine :).
