The ease to use, it's fast loading times which are great for my customers who need their shipments out quickly! I dislike that there is no way other than using an email address when creating new accounts or adding contacts into existing ones - this makes things slower as you have more steps involved in getting your account up & running with them rather then just one click button like most providers offer today (like DHL). We utilize eftcargos services daily at our facility so we can move loads from point A all over North America without having any issues along those lines.
