Price and rating as shown on Amazon when we collected them. Both change.

The Anti Barking Device M1 is a rechargeable ultrasonic bark deterrent in a blue casing, listed at £36.99. It takes the number 9 slot in this guide. Its listing carries a 5.0 rating from 43 reviews, and the rating breakdown on the page puts every one of those 43 at five stars — a clean sheet, with no lower rating recorded at all.

What the listing does not do is agree with itself. The fifth bullet is headed "WORKS FOR ALL BREEDS & SIZES" and then states that the device "doesn't work for over 50 pounds dogs". The specification table lists one lithium ion battery as required and included, and then answers "Batteries required: No" a few rows further down. The headline distance, 33 ft, is the same figure that recurs across this category. The bullets promise 5 modes and 10–40 kHz variable frequencies, while one of the reviews printed on the same page describes three frequency options. Everything below is taken from the Amazon listing and the buyer reviews shown with it — we have not tested this device ourselves.

What buyers actually say

Quoted from customer reviews on Amazon

“I mainly wanted something to curb our spaniel's barking when he's out in the garden and we're indoors, so the range was the big selling point. It genuinely reaches him across the lawn without any issue, provided there's a clear line of sight as the listing mentions. We've also used it on the covered patio when he gets worked up at squirrels. The automatic bark sensor is quite clever — it only seems to trigger on proper barking, not background noise, which is reassuring. Setup took seconds and there's nothing complicated to fiddle with. For the price it's been a really worthwhile purchase.”

Beverley

“This anti barking device has been a positive addition to our dog training routine. It is simple to use, and the three frequency options make it adaptable for different situations. My dog responded gradually. The device is lightweight and portable. The battery life has also been reliable for regular use.”
