@Michelle L  How often do you have to change the battery?

There's no greater or worse feeling Every time you see dust or REALLY ANYTHING of a small spec or a piece of your own hair tickle you And has you literally fully loaded with a flash light with new batteries(god forbid you run out of batteries). 

It is Tenant’s responsibility to test smoke and carbon monoxide detectors weekly and replace batteries when required.

What I like about it is the one time fee although there are sometimes new modules you can buy every year or two where they improve but it's a nominal cost.I also like the fact that you own the cd and program whereas some other programs they make you pay a fee online and if you stop using from them increasing the monthly fees you have nothing.

I had used evernote a couple years ago and it would put a drain on my cell phone battery.

They tend to pull out the batteries from smoke detectors for their personal devices.

I will start reading some books before taking the dive and learning how to structure by business module.

You could be sitting there telling yourself, “Heck I'll just install CO detectors” but what happens when the tenant removes the battery and do you really want to trust a cheap gadget with wide operating tolerances that may or may not alert someone in time?
