Windows 7: Sandboxie seem too good to be true?

Is it me, or does Sandboxie just seem too good to be true?

What is Sandboxie ? Maybe Sandbox security software for Windows?

Sandboxie runs programs in an isolated space in the hard-drive and prevents the program for making a permanent change to your computer.

I have never used sandboxie so I can't tell you if the program is the real deal but here is a review of Sandboxie I found on Google.

Are there any known programs similar to this one that actually have a legitimate reputation? By the looks of it, it just seems pretty new... Do you guys think I'm better off forgetting about it?

I know many users on here who swear by it, I have to admit I havent used it myself, but as i said, alot of Guru's on here won't do without it

A user called rogueamp on YouTube uses Sandboxie to test Mal-ware, I would think it's safe

Sandboxie is totally legit software. Used and respected by many.

Sandboxie is an essential part of my system. I use it daily. You can run your browser in it so if you contract a rogue virus, it doesn't affect your computer. Just close the sand box and it is gone. It is kind of like running a virtual machine without having to install an OS. If you do a lot of downloading and installing of apps, or download a lot of torrents, or just want to be safer than what you are, I highly, highly recommend Sandbox. It is a great app and I guarantee you won't be dissapointed. It has been around since around 2004 and I have been using for the past 3 years. Download the trial and use it. If you like it, buy it, if not get rid of it. I or anyone else will never know if you like something. Everyone has different opinions. I gave you mine about it and now if you get the trial you can get your own.
