Great tag but cheap ring fastener

I loved the actual tag. They're heavy duty and nice looking. The small ring fastener, however, broke after two days of being on my dog and his tag was lost. Going to buy another but just use a different connector to the collar this time

I used these for the jewelry in my store and have really liked them.  They have a sturdier string that a lot of other tags I've seen, and are nice and small so they don't distract from the jewelry.  I also really liked the gold color.  My only complaint is that the surface is very plastic-y, so you definitely have to use a fine tip permanent marker to write on them, and blow it dry or don't touch it for a bit before it's ready to go.  Otherwise, really nice tags.

The quality of the tag itself is good, but the text got easily scratched. I bought one for my cat. My cat wears a bell collar and the tag is next to the bell on his collar. The text on the tag got scratched after a while because it hits the bell.

The tags are great.  I had a big problem unscrewing the metal cable.  It is machined very poorly.

I picked up this tag for my 4lb chihuahua. The size is decently small for such a tiny little guy. The problem is the tag itself only lasted about 2 years before it got scratched and tarnished enough to be unreadable. Have even tried polishing it up. For the price I'd say this should have lasted a lot longer, but we do frequently hike and visit the beach. Thus 3 stars for an ok product rather than less.

This is the second of these collars i purchased. The first lasted us many months until our puppy outgrew it and needed a larger size. We received the new collar on December 8 and in less than two weeks, the tag ring came off and clearly was defective as you can tell that it came apart at a perforation. The actual collar itself is fine but not having the tag ring is a deal-breaker.

Good overall, but the ring around the drive falls off and is cheaply made.

The split ring that is included with the tag is extremely cheap / poorly made.  In trying to get it off the tag and replacing it with a more standard duty split ring to attach to my dog's collar, the split ring gouged the tag - while the laser engraving may be more durable than printed versions of this tag, it isn't ironclad - the tag is still subject to damage, etc.

The ring that comes with the tag sucks. The longest my two dogs were able to keep the tag on using the little ring that comes with it is about a week max.

The tags are so cute, we bought 4. The rings to hold them on the collar pull apart very easily resulting in us already loosing one tag. If the rings were stronger or if you put it  on with  a different ring, it'd be 5 star

Love these tags and what they say.  The lettering is very easy to read.  The only reason I'm not giving it more stars is because the tag is so heavy that it pulls on the s-hooks holding the tag to the collar or collar rings.  They ended up falling off after just a couple of weeks.

The tag is clear and robust. 5 stars.
The tiny mounting loop provided is a joke. Way too small for any dog medium sized or larger.

This product has a critical weak link: the plastic ring which connects the tags to the collar.  This plastic ring broke within two weeks of use.  I was lucky to hear the tags fall on the stairs.  If my dog had been outside, the tags could have dropped anywhere.  Tags are only good if they're on the dog...this ring needs to be replaced.  The plastic sleeve itself is great and I've kept using it but this time threaded a key ring though the hole.  Now I have silence and securely attached tags.

Have been looking for a strong, visible, and relatively inexpensive substitute for various luggage-manufacturers' rather weak tags for sometime, now.  I like these because the rings are strong, yet can be easily removed by yourself or an airport employee (if the bag is lost).  Four stars because if you're a frequent traveler, you need more tags to write on.  Even for a round trip you need to write on one side for your destination, and one side for your return.  BlueCosto isn't the only tag-maker that seems to forget this fact.

Main unit works very well, but the magnet and clip on the back are cheaply made and fell apart after a couple weeks of consistent use. If you're using it in the same location all the time, go ahead and find a good place to install using industrial strength velcro. It's worth the extra couple bucks

The tag is good, substantial. The collar it comes on shreds into cotton candy in a month or so, quicker if your dog scratches on occasion. Had to buy another collar, tap the eyelets with a hammer, and slide the tag on. NOW it works.

I love the cost of these, however after a couple weeks of use the tag is very scratched up and the ring it attaches to the collar with broke off while walking the dog.  Maybe a good idea for an older dog or calm breed, but didn't work good for my energetic husky/shepherd mix at all.
