Upload functionality doesn't work. Beware that if you want to put some money down to try it out, don't do it with Paypal. Their "Buyer protection" is as much a scam as ThunderDrive itself and they will not refund you. ThunderDrive itself has the usual issues with uploads not working, as others have pointed out. You may need some strong scripting skills to make it usable, but even then, it's uncertain.

This is really a fraud service that… This is really a fraud service that should be avoided at all costs. I purchased a lifetime membership a few years ago and kept my documents and other not-so-important but important notes on the drive. Now when I opened the site, it's all gone. Strongly recommend avoiding it. My two cents.

Never purchase Thunderdrive I have purchased 2 accounts in lifetime deal, one was on eu.thunderdrive.com and another one was on app.thunderdrive.com both accounts are not working, the eu.thunderdrive.com domain is now invalid and app.thunderdrive.com is almost unusable no option is working all stored data is lost never purchase thunderdrive.

ThunderDrive is dead + contact info The update from Roman A. Masaryk that ThunderDrive is completely down is true for me as well. app.thunderdrive.io no longer responds. At least prior to this I could see my files (but not download). All the site ownership info is redacted for privacy in the whois database, however there is an address on their data privacy page. It is a home at 4425 W Pinsapo Dr Fresno, CA 93772 and ownership of that property is redacted as well as it is owned by a public official. However, one could snail mail them at that address asking for a refund. Probably won't respond but who knows?

Aviod at all costs I subscribed to thunderdrive with their lifetime offer and it worked ok for the first 12 months however it is now impossible to access any of my files. I cannot download them or even see them. These are scammers of the highest order
