I am glad to purchase
"I am glad to purchase e-collar from Dogtra. So far so good. However, I am hoping that I could set up different level for different receiver because I have 3 receivers. You know each dog has its own different level, so I hope there is a feature to set up/memorize while I switch to different receiver; therefore, the different handsfree square has its own different level of nick. Thank you so much!"
