I hope it is better made than the three I have gone through (see my other thread). One just died and two have melted and ceased working. I've cannibalized two of them into one so I can change the battery out so I have one working, but doesn't look like it is long for the world.
I have to agree with Bruce on this one! All mine have had motion sensing capability, but had issues with heat damage. Others have had moisture issues reflected in customer feedback on multiple sites. With all the Smokefire hype, I hope they don't forgot all the customers that keep them in business.
