I am not very computer literate and still managed to install the app. The app is fairly simple to customise, and when i did struggle and want to make some changes to the layout/display on my storefront the customer service team (Bary) was excellent. He was patient, prompt, and although it took some tweaking the app is working smoothly on my site by my tests. Very happy. My Website is new and we are yet to see much traffic so i can only speak to the setup process as yet, we shall see how it performs as we get busier but to this point i cannot fault it.
