Review: Gen4 GDM works great! - Like the other reviews have said, it's using a gen4 GDM chip for the HF side, and a T5577 for the LF side. It's essentially the ultimate ring, with the two best chips on the market inside of it. Works great for almost every install I've come across, especially if you know how to 'downgrade' credentials. (literally just writing the wiegand in a different format)
Review: Works overall - could do with better range - So I picked this one for it's dual frequency capabilities. The preprogrammed IC 13.56 Mhz appears to be a Mifare Classic 1k 10 digit. The ID 125khz chip ships blank- this needs to be coded with a reader. The 13.56mhz function works with my digital locks - it works (after coding this into the lock) although the ring needs to be right next to the keypad. I then programmed the 125khz chip with a cheap reader/writer for the time clock. That also works, but it took a bit to get the reader / writer to work. Issue appears similar to the 13.56 chip being very limited range / low signal echo. Otherwise, after getting it going, it does what it's supposed to in a nice format (ie. I don't have to carry keys, fob or cards anymore).

## Features

- 1.There are 2 chips in the ring, one is ID T5577, another one is IC CUID.
- 2.ID T5577 chip is blank, it can not be used without written or copy.
- 3.IC CUID chip is pre-programmed, you can directly authorize it to work if you are administrator. You can also use it to copy your old IC card. If you have android NFC phone, you can copy your old card IC card without a copier.
- 4.Both ID and IC use 360-degree omni-directional sensing technology, the sensing effect is much higher than similar products in the market.
- 5.Our ring is made of zirconia ceramic material, which is very comfortable to wear.

### ⭐ Works 30% of the time.
*by D***D on February 23, 2025*

The “dual” does not work properly. You need to rub all over the ring for the sensor to sense the frequency such as 125khz. Waste of time, you’ll look ridiculous having a ring on waving on the sensor many times until it detects. Sometimes it won’t detect at all. These are garbage.
