I bought this a few months ago and would not recommend it. It is very cheap for a lot of storage, but there is no mobile app you can use. I can get along with this, but it only works about 50% of the time. When I want to upload files it is 50-50 whether the site even is available for upload. Then, if it is up, there have been many times my files have seemed to upload, but do not show up in the cloud.
Personally, I am staying away from these hit or miss lifetime subscriptions to cloud services. You just really don’t know how long they will be around or whether they will change the terms of the subscription. Also, I am not comfortable with uploading my data to these sites. Better to pay more money for established sites with less space like One Drive, Dropbox, Google Drive or Amazon.
