The developer support team are very helpful, quick to respond with any requests you have for clarification! Also they use PayPal which makes it easy if want payment in Australian dollars or US Dollars (I am located overseas). I really like that there's no limit from how many people can be taking screenshot at once - this was my biggest concern when researching other APIs as all others had restrictions such as having only one person take an image each time. Just make sure what order your scripts run first otherwise things will become messy after about 20 seconds :) Take advantage of their free trial before purchasing so see exactly what works best for you within the application itself and also ensure everything runs smoothly afterwards too. It allows me create website reports easily without manually uploading images into MS Excel/Word etc through bulk uploads via FTP.
