The best thing I like is it's ability for me as an individual user who doesn't have any programming knowledge at all (I am just someone using this software)to be able test my own website without having access to servers which would cost thousands per month! It was difficult when we were first trying out how easy/difficult they made things but once you figure everything else out its not too bad anymore - only took us 2-3 hours before getting used to what each button does etc so there isn;t much downside really if your willing enough then give them try!! We started off small where one person could do most jobs themselves however now multiple people help make sure nothing gets missed up front while still being flexible down stream should something go wrong later on.
