I'm sorry that happened to you. That really sucks.
Whether or not the extender is to blame would be debatable since the anchor point of the receptacle is not changing. The only thing that changes is a couple inches of the webbing is replaced by solid material. That should make no difference in its ability to hold a body in place when forces are applied. If we unbolted the OE receptacle from the floor and moved it up a few inches I can see a potential issue, but that's not happening here. No dimensions are changing anywhere. We're simply replacing a small section of webbing for the extender.
I love mine and have since bought more of them. They solve ALL the issues with these electronic nannies on modern vehicles (except for the horrible "3 horn honk") and on a couple of my vehicles with hard to reach release buttons they actually make it easier to release the seat belt. (This could also prove to be safer in a crash.)
