They answer technical help requests promptly and even are prepared to help users with the free accounts. I moved to Mega from another famous cloud store that was getting very irritating with poor file and folder handling. Mega allows much better editing and arrangement of files within folders. Also allows sharing links with non-members to view photos and download as required. So it seems it's very reliable and I have had few issues at all so I vote it very highly recommended for storing files safely. All nicely secure.
