Visiglo Red Nylon with White Led, Medium

I originally purchased this brand of collar from Ocean State Job Lot and they worked for a year or two. I looked online to purchase new ones and found them on Amazon. I first purchase a yellow and red one two years ago and they worked for the season. When I pulled out the red this season, it no longer worked. I attempted to change the battery but it made no difference. I ordered a new one and it turned off/on correctly. However, it would turn off on it's own within 5 minutes or so. I returned it and purchased a new one. I tested it as soon as it came, before I even took it out of the packaging. It turned on and then wouldn't turn off. It's like the button was crushed. I immediately returned it and have yet to order another. The brightness and functionality is great, but the quality is so poor. Would rather pay a little bit more for a better product.

Brighter and more visible than other pet lights which hang from collar. This product has a recessed on-off switch that is the weakest component of the collar. Once lighted, the slightest vibration of the collar turns off the light. I put it on my dog and it won't stay lit for more than 1 minute. As a design engineer I am disappointed they compromised a good idea with a cheap switch.

It's comical how bad this collar is. Can't open the clasp. A quarter of the lights don't burn and once turned on it would not turn off. Had it out of the box for 5 minutes, mostly trying to open the clasp, and went right back in. I hope they do not resell this collar.

I have now purchased three within the last six months. They last about two months then the on/off switch will no longer shut off the flashing. They are great while they work, but wish there was some way to correct this problem.
