I like that they are very helpful in explaining things to me when it comes time for implementation of my site speed optimization project! They also have good customer service - if you call them within 24 hours after your first contact (which is usually required), then there's no problem at all getting someone who can help out right away!! We got our website performance up by nearly 50% just from their work alone without any other changes or modifications being made. Their word press plugin installation was flawless as well so everything went smoothly once installed properly; nothing else needed changing/modifying during this process either which helped us save some money since not having to pay additional fees would be nice too ;-).
