  • What the frak

    Disappointing big time. This thing should be free. The tone selector is horrible because it's a slider. It jumps from 15 hz to over 200hz. So if you want to experiment with specific frequencies, you can't. Wish I wouldn't have wasted my money on this one
  • Scared away the noisiest mice...

    By Tympa
    We were staying in a cabin with some very noisy mice in the walls - chewing and scraping all night. I put my phone in the cupboard where the noise was loudest, and left this app running. The mice went crazy! They squeaked and squeaked and then ran to the other end of the house and stayed quiet all night. I don't know if it would work long term, but it definitely gave us a good night's sleep we wouldn't have got otherwise...

    It never worked at all, a waste of time and money!!!
  • Useless

    By jciek
    Tried for hours to find a frequency that would repel the mosquitoes but to no avail. Researched on the net the frequencies of normal predators, male mosquitoes, etc. and nothing worked. According to studies, female mosquitoes are not sensitive to ultra-sound and all previous campaigns conducted at big scales failed. Do not buy.
  • It' working

    I didn't expecting but it works so well. Just remember when you use it at night, don't put the front on the floor. I think the gray skin design of this app is for the repeller. Good luck, it totally work for me!
