I have unopened flea collars for 5 animals from Dr.Paws. I read reviews that said if you open the product and put it on your animal they will refuse to refund you. So, after reading reviews about animals being vetted due to sickness occurring because of ingredients in the collars I decided not to even try them and get my money back. I contacted customer support and was asked to send a short video and explain reason for return. I said we went with another product and simply changed our mind. That I had unopened product and wanted a refund. DENIED! My reply was F you. All spelled out. I've never done that. I've seen so many reviews about this product making animals sick and not working. Some reviews the animals have even died. I am not comfortable risking it. Also, the shipping label says it came from Illinois, but my tracking was from China. And it took 8 days, but that's within their time frame. So, maybe this will help someone else not eat their money like I did. They stole from me. Screw this company. Do not buy.
