I would like to write a second review regarding the ready treat dispenser. Clean Run has excellent customer service! After my review about the ready treat not working, they immediately shipped me a replacement with a return label for me to return the defective machine I had. I truly thought I was out the money and not having the device which I really need for training. I was able to pair the new device and it is working great. I want to sincerely thank Clean Run! Good customer service is hard to find these days and it truly makes a difference for this customer! I have ordered each of my dogs a harness from them and referred at least 3 people that have also ordered a harness. I will definitely spread the good word. Many thanks Clean Run!!!
