I have been looking for a deal like this on Appsumo for a while. Been busy uploading files the past three days and it works very well so far.

File transfer is smooth and quick. Moving folders and renaming works great. I'm not planning on using Ice Drive as a "working" drive, just a secondary cloud storage "just in case". Dropbox has worked fine but the lifetime deal here beats the $120 a year for 2TB at DB. Now I can reserve the free DB for clients to send me files.

I haven't had this long enough to try out the other features but so far it has earned five Tacos. If you just need secure cloud storage, the lifetime 2TB is a no brainer.
