Review on 🐶 Inoosky Ultrasonic Dog Bark Deterrent - Rechargeable 2 in 1 Anti Barking Device with Variable Frequency, Handheld Dog Training Tool for Outdoor and Indoor Use by Amy Wilkins

All in all a miracle cure for my herding dog. I only had to use it a few times and now it's just a case. Two things I would improve - come with a lanyard/wrist strap already attached (buyer can remove it if not needed). I can't reach it at all through the tiny slit. Make the keyboard lock button more accessible or press the button. I use this on walks and find it difficult to move the button back and forth. My keyboard is locked except when I'm near cars or other dogs so I don't accidentally press the key while it's in my pocket. Another idea is to get rid of the lock button but press two frequency buttons to make the sound (one just for the light).
