Ultra Sonic Bark Deterrent - New in Box!

I'm selling a brand new ELYFTI ultra sonic bark deterrent, still in its original box! Upgraded dog bark deterrent —delivering 3X the coverage to quickly stop barking, biting, and jumping behaviors. Ideal for anti-barking training, safer than bark collar, more effective than a dog whistle. Works for 97% dogs from 6 months to 8 years without hearing impairments. Train without pain using two ultrasonic frequencies (20–30kHz) and a pre-warning beep to gently stop barking, biting, or jumping. Designed to help your dog understand commands quickly — without using shock or physical punishment. It's powerful, safe, and portable, helping keep dogs alert, focused, and responsive during training. Features a bright LED flashlight with steady and strobe (SOS) settings for evening walks or emergencies.
