Very neat design and easy to use. I have 6 dogs so they react differently to the ultrasound. Some stop barking immediately but the others can carry on for a while. Its like an ultrasound dog whistle - some dogs get it immediately while others take longer. Its just a matter of patience and persistence. In all perfect.
