The user interface of this tool can be easily understood by almost anyone who has basic knowledge about internet technologies or computer software in general as it follows very simple rules but easy enough for any technical person to use it without much problem; you don't need to have prior experience using such an application as its simplicity makes things very understandable.
It's free so there are no financial issues involved if one decides not to pay for all available plans which include customization options, web hosting integration etc.; however I strongly recommend paying extra money otherwise they won’t make sure everything runs smoothly when needed since the support will depend entirely upon how many clients they get. We managed our client base better than ever before due to some customizations we made using their products (webhosting) plus other services offered by them.
