hecere T5577 or UID chip RFID Black Ceramics Smart Finger rewrite Ring 125KHZ/13.56MHZ Wear for Men or Women (T5577 125KHZ-19MM)

Works great

Works great. I'm 6'2" 245lbs, athletic, fits my first fingers on both hands and middle finger of left. I got bigger knuckles than my fingers and this glides. Comfortably and removes how it should. I do not have an RF copier. There are only a few rings on Amazon that are programmed like this one. The other one is a silver meteorite design. I programmed it to my Hornady RF rifle/shotgun safe. Works flawless like this companies silver one too . I wet sanded mine with 320 and higher grit to make it matte with the outer parts still glossy. This was achieved without taping. Just sand away.

I have purchased three of these rings. I was able to program one ring in about 10 attempts. The second and third rings took more than 30 attempts to program! I'm not sure if it's my reader/writer or the rings that are the issue.

First ring I received I could not program. I could not read or write it, with a couple of different devices. Thankfully Amazon makes exchanging it super easy, and I got a replacement the day after I requested it. I had no issue writing a code to the replacement ring, and the first couple of times I used it it worked great. Fast forward a few weeks later, and it still works...usually. I programmed it to work with both a gun safe and the door system at my work. Fortunately, it works much more reliably with the safe, but unlike even the cheapest of key fobs I've tried at my work, it has to be touching the sensor, and even then I often have to run it side to side a few times before it will read it. Overall I'm satisfied, but I wish it were a tad more reliable. UPDATE: Less than 6 months later it broke. Not even sure when it happened. I was sitting at work, and felt it pinching. took it off and there is copper wire exposed on the back and a giant chunk of the ring missing. Add poor durability to its highly unreliable performance.

Works great, coworkers surprised that I unlocked the door without a key card😂

I now own three of these rings in both the T5577 and UID type. Both programmed easily and have worked flawlessly. The only slightly negative thing I can say is that after only a very short time they are showing wear in the finish which seems to be common with these types of rings. To be fair, I wear them all the time, regardless of what I am doing - gardening, cutting firewood, etc. Bottom line, I would not hesitate to buy this item again.

***Update 2023.09*** My 2nd one just shattered on me. You can get by gluing the broken edges for a while, but once big chunks start coming off you will loose the chip and functionality. My 2nd ring lasted much longer (about a year), but I was also much more careful with it and got in the habit of taking it off during the day since night time is the only time I need to use it. I'll do a bit more searching, but will probably buy a 3rd ring if I don't find a more durable option. ***Original Review*** I bought this to use with my quick access safe (I purchased a programmed version). Within a few minutes of opening it I had it programmed into my safe and loving it! You do have to get very close to the scanner, but that is not a negative for me. After a few weeks I noticed a LOT of scratches on the surface of the ring. Not a big deal for me since I bought it for utility, not looks. About 3 months in I noticed a small chip was missing from the edge, which again was not the end of the world. I filled it with some glue and sanded it smooth so it wouldn't rub or cut my finger. At 4 months a HUGE chunk of it broke off, leaving sharp edges on the inside of the ring and a bunch of the copper wire exposed. I am currently seeing if I can get by with some kind of repair. I LOVE the functionality of this thing! With 5 little kids in the house it is great to know that they can't get into my safe, but I can at a moments notice without having to worry about carrying a key, fob, combo code, or finicky biometrics. I don't know if I will purchase a replacement knowing it will only last 4-6 months, but since I don't know of any other similarly priced product that is better constructed out there I am leaning towards yes. Is it worth $8/month?

Worked like a charm. Lets me in and out of my door and it fits.

I have been using this as my daily for opening doors around work, the only two downsides are: It is pricey for an RFID tag (but I knew that when I bought it) The ring is the coil, makes sense right? But then how do you align the coil with the reader? I've found there is an angle that works okay with most readers but you cannot simply walk up to readers and 'fist bump' them because then the ring is at 90% to the reader and it won't pick up. EDIT: Nearly a year later, it's still working. EDIT EDIT: It is April 2025, it is still, still working.

Great item which looks good and functions perfectly.
