I have to admit, I was a bit skeptical about this Pet Hub thing, as I found this on a Groupon. However I was so thankful I had this. I recently moved to a house, and Frank has been enjoying the back yard so I let him stay outside while I went back to work for an hour. He is normally in a kennel so this was a treat for him. I went back to work and got a call from my boyfriend asking where Frank was. I told him the back yard.. his response made my heart drop. Frank was missing!! I rushed home, and ran through the neighborhood looking for him. At this point I completely forgot about his tag. My phone vibrated, I looked at this and there was a map and phone number for the person who had frank. He was just around the corner safe and sound. I was sooo thankful for this tag. I tell everyone about Pet Hub. So if you are on the fence about this product at all BUY IT!! ! it is great!! Thank you Pet Hub for helping find Frank!!
