O2 sensor bung with CEL elimination

Anyone used one of these before? It's basically a spacer that goes between the bung in your downpipe and your sensor. It has a tiny little cat in it. Supposedly it eliminates check engine lights.

I used a very similar spacer on my F32 when I was catless. The car would still only last about 60-100 miles without a CEL popping up. A flash tune was ultimately the only viable solution to permanently get rid of it.

If you are open to getting a catted DP, Active Autowerkz makes one that has a no CEL guarantee. That's what I'm running on my car and haven't had any issue.
