Short summary: cheap, bright, small.Has two or three colors. Most noticeable colors are red and blue. People says we've got a police dog now =) It is small enough to not bother the dog. But it has very bright light. It's almost like a small torch excepting that it blinks.It has a rubber gasket - probably it is water resistant, but I didn't test it. Has a handy carabiner, so one can rehook it to another collar at any time. Could be used as a safety light on a back pack or bike.

Very convenient thing for walk with a dog in the evening if the dog escapes, always it it is visible. Blinks red and dark blue color alternately. The parcel in a small package for 23 days has come to Russia. I hope, the battery will suffice me for a long time!

This product is wonderful. Fits easily onto the collar and lets you see the dog from a very long distance. It does not harm the animal as it does not affect the dog's eyesight or field of vision. May also be suitable for other uses, such as playing tennis in the dark, provided that you can find a way to attach it safely around your own neck!
