Keeper cargo tie down anchors - good or bad??

Has anyone had any experience with the Keeper "Bull Ring" tie down anchors? Example of the product can be seen with the below link.

I'm a new dirt bike owner and experiencing the Tacoma anchor point short-comings and dont feel like dumping my new toy on the road when one of the weak rail system sliders fail. I've read up a bunch on the floor mounted d-rings and the www.jpmetalfab.com option, but haven't read anything on the Keeper series. I've seen these on Chevys and Fords, but not on Tacomas. The Keeper setup is great (if it works on Tacomas) because the anchor points will be extended as far out as possible, which is good for dirt bike hauling.

Thanks for any input folks!
