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.
