It works fine as long as I remove the black rubber sleeve that covers the rigid shank of the extender. That black rubber sleeve is loose enough that it slides down into the latch of the factory seat belt buckle and depresses the release button, causing it to disengage, which is VERY DANGEROUS!!! Luckily, I figured it out fairly quickly and removed the rubber sleeve. These were obviously not thoroughly tested before offering them for sale! With all that said, I haven't had any issues whatsoever with the extender since removing the black rubber cover sleeve! Ideally a heat shrink wrap sleeve would work perfectly as a replacement. Picture #1 shows how I'm using the extender without the black rubber cover sleeve. Picture #2 shows it with the sleeve in the up position. And Picture #3 shows the sleeve easily pushed down into the buckle latching area which results in it depresses the release button, causing it to disengage from the factory seat belt buckle!
