ULTPEAK Dog Bark, Upgrade Ultrasonic Anti Barking Device, Rechargeable Bark Control Device, Waterproof Dog Barking Deterrent Bark Stopper with 3 Adjustable Levels (Black)

So disappointed with this! Tried all the frequencies and nothing worked. Charged as per instructions and all look to be working with the correct light colours.Don't waste your money.

Worked a dream straight out of the box. Well after charging it of course, have not needed to recharge so it seems to last the month. Did not no wether it would work because our dog is 13 years old ! but as soon as it was active, not a peep didn't even notice a work in period where she barked it just stopped right away . Brilliant product would recommend to anyone

Doe not work at all - left on for the dog to stop the barking when we go out - we left a recorder on while we were out to play back and see what happened!!! well what happened was we paid good money for something that doesn't work, when we played back the recorder the dog was barking & howling 25 seconds after leaving the house & for the full 35 minutes we were out - total waste of money - I hope the manufacturers of this device read the review

It was working perfectly for one month but when it needed charging it wouldn’t charge. I tried different charge cables and power ports in my house. Can’t find a way to contact the seller from my order so this will have to do!

STILL BARKING

the cost does NOT matter. The product does NOT work

Didn't work, even when it's 2ft away. Returned.

Does not work.
