Review on HECERE Ceramics Rewrite 13 56MHZ 20MM: Advanced 13 56MHz Ceramics for Enhanced Performance by Dennis Goozmer

I could not program the first ring I received. I couldn't read or write it on a few different devices. Luckily, Revain makes replacement very easy and I received my replacement the day after I requested it. I had no problem writing code on the spare ring and the first few 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 the gun safe and the door system at work. Luckily it works much more reliably with a safe, but unlike even the cheapest key fob I've tried at work, it has to touch the sensor, and even then I often have to rotate it back and forth several times before it reads it. . Overall I'm happy, but I wish it was a little more reliable. UPDATE: Less than 6 months later it broke. I'm not even sure when it happened. I sat at work and felt it tingling. removed and the copper wire is visible on the back and a huge chunk of the ring is missing. Add poor durability to its extremely unreliable performance.
