The best part about lepton is its flexibility. It can handle almost every type of website or web application. It's easy to use as well. There are no major problems that I have faced so far. If you are looking for a very robust content management system which is easy to use then you should definitely go for it. We are using lepton for our e-commerce website. It has been great for us. The support team is always there to help you. The only thing that I dislike about lepton is the price. It is quite expensive compared to other similar products out there.
