I brought it 2 years ago and it kisll all the mosquito.
I am using it from last 2 years and it is working perfect without any problem there is no need for service of this machine its a small cute looking machine and it is very effective to it kills every mosquito in 20 minutes and its smell is also good .
it is having two modes one is normal and one is for fast working and fast mode takes more refill and normal one take normal usage.
we have to refill it 2 times in one month and it is not costly it is of reasonable price.
it is build of solid material because in 2 years of usage it has been fallen from arm height but never got damaged it is a solid product.
the only drwaback I think is that it takes too much time to kill pest and insects this problem should be improved in the coming models taht will help it in being the best in its segment otherwise this is the best.
