I use them all the time on heavy smoke and pet smell houses and it works great in neutralizing the odors. 

I had a stupid tenant make a comment to me about smoke alarms and kind of to the tune of if you put that back up in the hallway and it starts beeping I'm just going to rip it out..I called the fire department from the parking lot,, said it was a non emergency,, that a tenant had threatened to tamper with my safety equipment and wondered what to do.. they came out and talked to the tenant right away.. never another word was ever mentioned from that jerk again. 

The only challenge is replacing batteries, but I schedule it for once a year along with my smoke detectors. 

Say you buy a shell dark building for 600,000. 

They look a little dark and a little blurry.Staging looks nice.4,000 views since it's been listed. 50 people have saved the unit on Zillow.

They had dogs that they apparently never let out or cleaned up after, the worst smell I have ever smelt and they smoked in there also. 

I am focusing on using greige paint/white trim, dark vinyl plank floors and newer light fixtures to create a look that is very modern.

If the lease is vague check your state laws and post a notice for entry with 24-28 hours (again refer to state laws) to perform a general safety inspection.....say fire and smoke detectors.
