Review on 🐶 Illumifun LED Dog Collar: USB Rechargeable Glowing Necklace for Small, Medium, and Large Dogs by Jessica Williams

There were three things I didn't like about this collar. The first is specific to my dog; He has very long fur and if I put the collar tight around his neck, the collar would be tucked under his fur and you wouldn't be able to see the light. The second question is, they're not hiding much. You have to cut off the collar to change its size; which I think is fine as long as your dog isn't an adult. This makes returns more difficult, but other than that, it's the same as buying a collar that's exactly the right size for your dog. The third and biggest design flaw, IMO, is that there is no clasp or anything to hold the collar in place. You just slip the plastic pipe over the 1/2" diameter plastic tab, which is slightly smaller than the pipe's inside diameter, and hope it stays together. My dog was running around the yard for about 5 minutes before the pipe burst and lay in the middle of the yard.
