Its a heave for mosquitoes where I am currently living. We are using 2 machines in same room. Apart from this brand we tried almost all brands but not useful to our type of mosquitoes.
Coil is highly effective but creating a unhealthy seen you cant breath easily also. All outs flavour will not effect your air system. So always comfortable to use in night. For kids also it is not so much harmful as compare to the coils.
