Review on Flashseen LED Dog Collar: USB Rechargeable Glowing Pet Collar for Night Safety by Ashley Gonzalez

I bought two of these colors to keep an eye on when I'm working at night. For that purpose they are great. If your dog has a lot of fur, like a collie, you may not be completely satisfied. But if you put it in blinking mode, it really helps. This color cannot be used with a leash as it is very easy to adjust due to the LED strip. It works like a second collar for the light. Has 3 lighting options. Fast flashing, slow flashing and steady light. I've had these collars for 3 weeks, I use them every day and charge them once a day. So far I'm happy with the quality.
