Neat looking product that comes in a nice gift box. Easy to set up and use, rechargeable and has a range of sensitivity options for all dog sizes and bark volumes,I tested the collar first to make sure it wouldnt hurt her (first time I have used a bark collar) I put it on the settings it was recommended in the booklet to suit her. Not long after I left to go to the corner shop and see if she would bark, I have an indoor camera and was watching her, she started to bark and the collar beeped, then vibrated. As soon this happened, she stopped barking!!
