DOGNESS LED Dog Collar, USB Rechargeable Lights, with 3 Glowing Modes for Night Safety, Water Resistance, Adjustable for Medium Large Dogs, Blue, Matching Leash Sold Separately

I bought for my boss dog a huge 220 lbs mastiff. It was like a BD party for this "baby". Everybody was impressed by the collar how cool it looks like on this dog. And when evening is here - light is turned on and miracle happened.Quality - good, solid material, a bit padded from inside which makes it more comfortable on the dogs neckSize - just read description, seller wrote a correct measurmentLight - easy to tern on/off, easy to recharge with USB cable, lasts 2-3 hoursWhat I would like to be improved - the actual pattern on the collar which is simple strips, I would like to have a choice between stars, moons, planets, flowers, etc.

Difficult to adjust the size, studs won't fit under clip.

Just got this collar and it looks awesome--durable. Will follow up soon with another update.

Bought 3 together for my dogs, after trying to charge all 3 for an hour only 1 worked but only on 2 settings. When the 3rd setting was selected the battery died after 2 flashes and wont come back on.The other 2 only work while plugged into a charger

This is a good collar to have to make sure you're seen at night! the lights can be all green, all red, or alternate flashing green, red, green, red...I love that it can be charged with a normal mini usb plug, many other collars use batteries and are not only expensive, but a pain to replace. I feel much safer having this collar on my pup in the evening or in the dark! Also it's really cute in the daylight, the lights look kind of like pearls and don't look like lights that just aren't on,
