The first luminous collar, which provides with completely satisfied. For our two dogs I have each brought a necklace, and both serve their purpose is always to complete satisfaction.
Very bright LEDs, yielding at night in some 100m distance still can clearly see our stinker. At the same time the internal battery is also good sized, so that the luminance up to about 1 hour can still be received well maintained.
Charging via the USB cable works well and pretty fast (about 30 minutes), but no charger is included. A simple socket USB power supply is sufficient but.
Finally, the shortening and customizing work on each dog very good and easy.
Perhaps a minor complaint in the end: The locking mechanism is very stiff and thus awkward to use, so we make the collar is not on, but draw directly over the head of the dog. As a tip, saying, cut not too strong, otherwise it will no longer fit on the head;)
