Unfortunately I ran into a few problems when I first installed this extension, which were in the main down to my server environment and incorrect configuration on my part. Geoff in support has been fantastic and very responsive. There is a lot of developers on this site that could learn a lot from him. If I install an extension and I run into problems and am unable to resolve them my first point of call is the developer and if they ignore me then its generally uninstall which is a shame. However here I am confident that if I do have an problems or suggestions they will be listened to and acted upon promptly. This extension is just what I was looking for and has loads of features to make it invaluable, topped with brilliant customer service I cannot recommend it enough 10/10.
