Anybody have experience with the SwingBox ?

It meets my criteria of not being too obvious, seems secure and convenient, and allows some storage below it to allow for carrying long items. I'm wondering if carrying a heavy load behind the rear wheels would cause problems or change handling characteristics. Would the rear end tend to break loose on turns to extra weight behind the wheels?

Thanks in advance.

 

still cant figurew out what it does

 

I give it a thumbs down--just my opinion--you know what they say about opinions
