Just bought a Litey Leash at Walmart today. My leash lights up blue. It's super neat when I'm walking my dog at night. The cost was very affordable, and I now plan to buy one in every color available. I'm now highly visible on my street. I plan to give Litey Leash as Christmas presents for my friends who are dog lovers. Great product! Pretty funny seeing people looking out their windows and cars slowing down to look at that string of lights!
