Works perfectly and also gets updated (bugfixes) and upgraded (new functions being added) very often!
Ease of use
Very easy too use although it's very complex (you can do a lot from maps to ticket-system, etc.)
The support system is awesome - haven't seen anything like that in years! You write a ticket and get answered and even problem-solved quick!
Value for money
Awesome value for the money spent - I renew the subscription every year and it's worth any penny!
