I have my band Trixie Light Blinking - bought Orange M / 42 cm 1pack because my dog has broken its previous light strip. I then times gained me a different color. It answers the purpose The luminosity should be visible at 200 meters, quite frankly I can not testify. It is indeed seen in the dark as it flashes, but the luminosity of 200 meters, I find then very low. For my circumstances evening to go for a walk around the block, it was good enough. For trips in the dark in the woods or on the field, I would recommend more light strips. It has to be unfortunately charged nor the possibility wired, but runs on batteries and can even blink at one stage. Other settings such as continuous light or so, does not exist here. Most even the ends light up where to go for on and off switch. Otherwise, you can see it rather weak. The color itself is fine and the luminous tube can also turn good. It is easy to wrap around the dog's neck and the notices it hardly because it is very easy. It can not be used as a training collar, but is used only for better visibility in the dark. To replace the batteries retracts the two ends and pull gently back on it afterwards stuck. The Bank neck I could out of the box put into operation without a battery having to use. Only I had to put in the plastic housing a loose end. However, the light ring is not sensitive to water. The luminous band fits well around the dog's neck and is not too big. It is not too tight and not too far to obstruct the dog. The price is still too high in my opinion. It does what it should, I think, there are better light bands with more features and better visibility, which are not that expensive. So I can only recommend this restricted light strip, also give points deduction and find the price too high. There is a band of different sizes.
