Considering the price I would give 100%, but current edition lacks some basic features (last minute offers e.g.). Wait for upgrade.
Ease of use
Very easy, intuitive navigation, good tooltips, simple design
EXCELLENT. This is my reason for buying E4J products. Marco from product support is always willing to help and answer within minutes.
Quick setup guide is good and helps in the first hours. Complete documentation explaining all options, variables and connections is missing
Value for money
The best product per buck one can get. Full reservation system for the lowest market price, no subscription and lifetime updates.
