My experience makes up a very long story, and I would go into it but I figure no one likes to read a lengthy review and more people will get the message if it's shorter. So here are the main reasons you should NEVER buy anything from this website. 1. The product comes from Singapore even though it is an Australian company and it took an entire MONTH to arrive at my doorstep. 2. The packaging was clearly fake and the collar itself was a light grey (almost white) and had a gross residue all over it. Shortly after holding it, my hands started to burn. 3. I tried to post a review and get in contact with anyone from the company, and nothing happened. They wouldn't publish my review and they only seem to approve the 4-5 star reviews they receive. This website and this company suck, and they are frauds. Do yourself a favor and go to your vet or a pet store and buy the real product and don't throw away $40 dollars like me.
