Shyam Innovations Supersonic Dog Repellent System, 300 Variants Very Loud & Noisy Frequency Sound, Solution to Keep Street Dogs Away, Dog Deterrent Control Device for Outdoors (2200 Sq. Feet Area)

Not at all good product. Creates a noise which bother humans first. Rest on animals it has no effects. Also please don't go for instructions as mentioned. As per instruction you have to wait 1 month for its effects and by the time return policy expires.

It's a Jugaad -No technical details mentioned on the product, very poor design (Zero engineering), I bought it after consultation on the number mentioned on the product and I thought the Ultrasonic Sound will not be heard by the Human, but the noise of this product (even below the sound level 1) is very sharp and very distressful. Used it for many days - but no visible result.

This product is a complete waste of money. Despite using it, the dogs were still in the area without any problems. Not recommending this product. Does not work.

The media could not be loaded. It’s very noisy , you may use in the night to push away dogs to sleep but then you can’t sleep because the noisy it makes too loud for humans as well. It bothers more humans , not dogs. They don’t even give refund

Not good for human.Cats are comfortable with this and roaming around.Not sure about dogs.

Not worth its total waste of money

Tried it for weeks. The noise became a trouble for us and neighbors alike but didnt work on the dogs.

It's Too Noisy, Ultrasonic sound should not be heard by Human but it's like speaker noise
