T R Lane Roll bars on ebay

See item 270304412850. Any one know, or have opinions, of this? I suspect it’s better than nothing but not at good as some because it attatches to parcel shelf, not rear structure. And could you / would you stick a harness on it? The seller is new to ebay so I’m a bit wary.

There is a discussion on nutz about these

here

I wouldn’t trust it in a roll over or for harnesses

 Thank you. Will save my cash for now then.
