Could be the reason, I don’t know what the real reason is. I’m not selling these.
I was looking at the reviews for these and I found that people actually installed these to pass Fire Inspections. (But its not UL listed?! How the…)
Anyway,
It is listed here because a lot of new collectors (and I mean a lot ), fall for this “Scam”. (Well it is but also not. It depends on many things. I just don’t like using the word.)
Like I Said before, There are many alarms that are way better and at the same price.
