The software is very comprehensive, well laid out and easy to use, and FREE! Most other vendors charge a pretty hefty fee for their client management tools. 10zig's is better than others I have seen and it's included at no charge!
A very minor thing - sometimes the sharing/permissions setup on ImageStore can be slightly confusing - but it is a one time automated setup and a non-issue afterwards.
Do not let the fact that it is free make you think it is a lesser product. Try it out and see for yourself that it includes features some others do not, and definitely has the capabilities that the expensive ones have.
The client management software really saves admin/IT folks a lot of time with remote management, template rollout, shadowing users for support, etc. This benefits not just the admin team, but also provides the user population with a more coherent "standard" experience no matter which device they use.
