Anti Mosquito - Sonic Repeller App Reviews

I use this app all the time. I live in an area that always seems to be heavily infested with insects and mosquitos, so I was thrilled to find this app one night while looking for different apps to purchase.

Its really a fake app like all the reviews here are fake. Its disappointing because all these reviews made by one person and posted at the same day 28th March 2016. Apple should remove these types of fake app.

Does anyone else find it strange that all 30+ of the recent positive reviews of this app were posted within one day of each other? Hmmm... Also, this product was featured on all of these news sites... because it doesnt work!
