I would recommend mailbigfile.com to anyone, the free service is great, but the business service offers great value for money when you have loads of large files to send and you need a trusted way for them to reach their destination!
Never had any trouble using or receiving. Works great with firefox. Uploads fast and sends fast. Love that it saves my contacts. I use the same ones over and over. A must have for the workflow. Saves money sending files internationally! Trust the files always get through and downloaded in a variety of countries. Love it!
