I have been using this product from a long time. But in last few months when the number of mosquitoes increased I find that it is not working. So I purchased mosquito net. That was a relief because rainy season has started. Then I decided to use this once again and this time I changed the machine. To my amazement all mosquitoes disappeared. I now regret purchasing mosquito net. It is working very better as it used to show results earlier. I was very happy once again.
The other thing which I like about this product is that it does not give any kind of foul smell. I never noticed giving any bad smell. It also has not affected my breathing and sleeping.
I think it is a very good product to keep mosquito away. Other good thing of the product is that it does not cost high.
