BlazinLight Up Dog Collar - The Original LED Dog Collar - USB Rechargeable - Waterproof - 1,000 Feet of Visibility - Dog Collar Light for Small, Medium, Large Dogs - USA Brand

My first Blazin' collar purchased was the purple one in 2019, back when it was Blazin' Bison, and it still works GREAT.There is wear on the on/off button cover, but it does not affect its function. USB port cover intact. I have since purchased several more colors and have given them as gifts, too. We have purple, light blue, red and black. The black has white LEDs and is the brightest.I only use these collars as visibility, which is probably why my purple one has lasted so long. I use a wide Martingale collar and a stout leather traffic lead to walk my 80 lb Rottie, and slip the LED collar(s) on/off for walks. We don't walk in the rain, and my dog doesn't swim, but LOVES romping in snow. Which we got a lot of in Buffalo last year! (No snow as I write this now)Visibility for walking at night/low light is great. I only use the flash if foggy and when off-leash in my dad's large, rural back yard. I often stack 2 colors for added visibility.I purchased LED sashes from a different seller for myself but was disappointed in the visibility. So, I purchased 2 small size, light blue collars and put one on each arm over my coat. We walk by a school with crossing guards early in the morning and it is quite dark in the winter; the crossing guards wanted to know where I got my arm bands, LOL.A couple of reviewers mentioned difficulty or impossibility of adjusting the size of the collars-I have not found this to be much of a problem with the large collars or the two small collars I purchased as arm bands. It DOES take a little extra effort to get the junction of the LED portion and non-LED portion thru the adjustment buckle; by angling it so it's on the diagonal going thru the buckle, it's easier to get that portion thru the buckle (see pictures). Once that portion is thru the buckle, very easy to adjust.I LOVE these collars for the visibility, ability to recharge and ease of use. I think they are a great value, and the 4+ year old collar works just as well as the newer ones. All of my collars seem to hold charge quite awhile; I think I have charged the purple one maybe 6 or 7 times since 2019.

Overall, these are excellent LED collars. They are very well made, reliable, and quite bright.I have tried 5 of these collars in various colors, trying to find the colors that are the easiest to see on a dark night from a far distance. The 3 I have settled on as the brightest and most visible are definitely the pink, the blue, and the green. Based on my personal experience, I have found these 2 colors NOT to be as visible in the dark: yellow and red. Just my take....I've been using these collars about 27 nights a month for the past 16 months. There have been a couple minor problems, but they are minor. These collars definitely still earn a full 5 stars. They are worth every penny and I think are actually a really good value.Minor issue #1: Occasionally somehow the dogs can turn these off. I don't know how, but they do. (Or if the dogs aren't somehow pressing the switch to off, then maybe the lights are going off themselves?) This happens rarely -- maybe once every 4-5 months -- and is not a big problem.Minor issue #2: There is a well designed rubber nub that fits into the USB port to protect it from dust when the collar isn't being charged. The "hinge" side of this nub eventually fails from normal daily use, and the nub falls off. Not a big deal. I've found the USB port still doesn't get too dirty, despite almost nightly walks on dirt roads.Be advised these collars are LONGER than you would expect. My dogs are about 60 pounds, not little dogs. For my first purchase of these collars I bought size Large. They were extremely over-long, but the collars are easily adjustable and I made them work fine. After 14-15 months of use I noticed the collars were not holding a charge as long as they used to, so I bought a new round of them, this time size Medium. (For the first year or so the Large collars would hold a good bright charge for about 10 hours of use. Beyond a year of use, they were holding a good bright charge for only about half that time. Also, on the pink collar 1 LED had burned out -- but only 1 of many, and this was no big deal.)When I ordered the new round of size Medium a couple weeks ago, they were the perfect size (very slightly too long, but again easily adjusted to make them a bit smaller).Here's the theory I'm going to be testing: Since the Medium collars have fewer LEDs than the Large collars, I'm guessing the charge is going to last longer. (I'm guessing that since the battery will be supplying power to fewer LEDs, there should be a longer time between recharges.) I'm hoping my theory will pan out. These brand new Medium collars are very bright and holding a strong charge for 10+ hours since they are new.Since I often walk dogs off leash in isolated rural settings at night, it is imperative for me to be able to see my dogs if they wander away. And I CAN easily see them from quite far away - maybe 150 yards away. Likewise, when I walk the dogs on leash at night in town (often in the street since we have almost no traffic), I want cars to be able to see them. (The few nighttime drivers in my small town slow down and some of them tell me from their car window how much they like these collars. And people who are out walking or sitting on their porches have given me many favorable comments. These collars are REALLY visible from a long distance away and easily draw the attention of onlookers.)I have tried many different solutions for lights on my dogs' collars over the last 10 years. For a long time, I used various brands of clip-on LED lights. Not very bright. Overly large and heavy. And they quickly ate up little lithium disc batteries (which were hard to change). But they were the best solution I could find. When I discovered these LED collars, I tried them and found out they do a very good job.By the way, if you REALLY want to make sure everybody sees your dogs, select the blinking lights setting. I do this in town. Nobody could possibly miss seeing your dogs when those lights are blinking. In the country, where there are no cars or people, I use the solid light setting, which works fine and is less distracting.After many years of trying many different products, I feel like I have found a really good solution for making my dogs highly visible at night, even from far distances. If you're on the fence about these collars, my personal opinion is that you'll be very happy with these collars for your dogs.

This dog collar, is very nice and made really strong especially the snap that clicks into each other. Heavy duty plastic and really locks in for safety I highly recommend it, and that LED lights are very bright and visible at night I picked the red one and I am very pleased with it and so is my dog very nice.
