About effectiveness.
Doesn't work properly and condemn. It doesn't kill any cockroach just it will unconscious for 20min. It doesn't effectiveness to mosquitoes also. Waste of money buying this product. Company must take care of this issue. It will go to unconscious after 10min of hitting spray on it.
About ease of use
It is handy and very comfortable to use but the button spray is hard to press some times Thats very big issue and doesn't work as you expected. Waste of money.
