The ability for customization is great! I love that you can add your own products, categories etc right into cart looom's database without having any coding experience or knowledge of html/css - very user friendly!! It also gives me peace in mind knowing my site will be protected from hacking since it automatically updates when i do anything significant like adding new product codes (which are extremely important!). There could potentially have been some more advanced features such as tracking customer behavior but other than this there aren't too many issues at all. My biggest issue was finding someone who knew how to use software well enough so they didn’t make mistakes which would cause them not being able fix certain problems quickly because their expertise wasn” t up-to date either. If anyone has no prior programming skills then definitely go through one tutorial before going forward using something complicated just incase things.
