Query: NOT Password-Protected

I should have read negative reviews for this item before I decided to order it. As other reviewers have already stated: this memory stick doesn't have U3 software installed on it anymore, therefore you get NO password protection - this is just your regular 4 GB flash drive. I will try to install free USB Secure software on it and see if it works. If it doesn't, I will consider returning this item. Not happy at all.
