Barktec Ultrasonic Bark Control Device 240° Pro

I found the product easy to set up. Easy to charge. It works well with my dog. Unfortunately there are two other dogs in the household, who seem to be uneffected.

It worked excellent first couple of days but now the barking is back

Our dogs go nuts whenever a delivery guy comes a round. We thought we’d give it a go. It does work, when they start barking they definitely react and stop from the sound it makes. We’ve been home with them since it arrived, so their barking hasn’t been that bad. The real test is when we’re both back at work. We'll have the monitor turned on and see how they go then.
