Very strong at first

The scent is very strong at first, but after a few days it will settle down. You really have to push hard on the button at the back to activate it. It didn't last 45 days as advertised. Maybe a few weeks at most. I used one for the washroom and one for the bedroom. Yes it is suppose to be for small spaces, but it worked well in bedroom. I got this on sale for $3 for a 2 pack. It is usually about $7. Not sure if I would buy this at full price.
