Delivery was almost instant, the device turned out to be slightly larger than I expected. If there was a strobe light instead of a flashlight, it would be more interesting.

Unfortunately, it does not work on dogs as described. The use of this product caused a greater aggression of the dog. Despite the information about the free return, they want to send the product at their expense directly to china, rating 0/5 🌟 I do not recommend product and store

Everything is as described by the seller, I recommend everything is good as described by the seller, I recommend everything is good as described by the seller, I recommend everything.

Made of durable plastic, with type C charging batteries. It emits ultrasound because the blades react. The sound is duplicated in two modes by the vibration motor, there is a flashlight. I will use it for dog training later.

ok, in real life it seems smaller than in the pictures, good plastic. It makes an unpleasant squeaking sound. The cat avoided it, haven't tried it on dogs yet.
