Me gustó mucho el collar para mi perro Dante, le queda muy bonito y se ve fuerte y resistenteIt's light and so easy to clean. It looks comfortable on my dog too.I didn't purchase this for the tag feature, I would have been sorely disappointed. I purchased it because it's waterproof, easy to clean, and the glows in the dark so I can see my black dog at nightLove this collar. It glows so beautifully. My boy does not stay outside long but just from going for a walk it glows for a long while. I can see him running around when I let him out at night and when I get up in the middle of the night it’s still glowing and I don’t trip over him. I did leave it in a window, in the sun for a few days when I first received it to get it charged up. Once it has a good charge it doesn’t take much to recharge it. It is super flexible, easy to clean and perfect for the pool. He even managed to get it off one day and I went looking for it in the dark and was able to find it without a light. As soon as they get more XL collars (he’s a big boy) in I’ll definitely purchase another one so I have an extra.The material, when clean, tends to be somewhat sticky or grabby. It would grab & snag my dogs fur, and made her visibly uncomfortable. I used a lot of baby powder to give it a less sticky coating, which seemed to help for a while, but needed re-coating about once a week.Also, I got the collar so I could see my all black dog in the middle of the night. IT DOES NOT GLOW for more than 30-45 minutes after exposure to the sun, so it was completely useless to me. She quickly out-grew the collar & I tossed it in the trash.I love this overall collar, it’s waterproof so when my dog randomly jumps in our pool I don’t have to worry about the collar souring later if I don’t immediately wash it.The clasp is durable and fun to use, my included concern is since the two pieces do stick out is when she lays down if they poke into her neck.The glow in the dark part was not the reason I purchased this collar mainly because I did not expect it to work very well but it glows very bright after she comes inside and the sun charges it. Also often when I wake up in the middle of the night I can still see it glowing. Although I would not purchase it as an alternative to a reflective collar if you are using it for going on walks or in an instance like that.This collar is great as far as durability. The glow in the dark feature doesn’t really work that great. As far as brightness goes it glows. But, not enough to save your puppy from being seen easily at night. Because of the material it is very stiff so needs 2 rubber holders (I guess you would call them. After sizing the collar). The App is a total scam! I downloaded on my phone, paid for premium subscription. Which, cost’s 3.49/Mo but that’s the only way to get to really get anything worth having a QR code tag for your puppy. It never let me login. I tried to contact support 3 times with absolutely no response back from them. Had to contact Apple and get my subscription cancelled and money back. They also be it is not a trusted APP.I would not suggest in any way buying this product!Was looking for sturdy waterproof collar for my pup because she frequently gets in the water on our hikes. I’m very happy with this purchase! It’s easy to clean and not super stiff and uncomfortable like some waterproof collars. Highly recommend! And it glows in the dark!
