The software despite bugs along the way (fixed quickly) is good. It's simple, works well and if your someone who bought in early like myself from V5 the pricing is decent and simple.
They annoyed a lot of people by charging to upgrade from AhsayOBS v6 to AhsayCBS v7 - myself included, however it was publicized well and the money was used to fund the complete re-work of the server side of things.
V7 is MUCH better than V6 for both restore and backup speeds (now block based).
The company is now working hard to resolve issues with their support not covering European time zones fully.
