Unintuitive, hard to use. Wasn't clear what I could clone and what I couldn't, and I couldn't figure out how to make the switching write properly.

I used it for my access controlled front door and bedroom door I have had no issues with proximity so far the two buttons that have been programmed are working as expected.

I bought these to consolidate my collection of compatible RFID cards I use for various entry control systems. You WILL need a special device to program these. They don't program themselves in any way. I just happen to know someone who has an appropriate programmer, so I didn't need to buy one (or learn to use it) by myself.He was able to program three cards for me. Basically, they turned out to be easy to program. And all three of the newly programmed buttons worked. However, one of the readers I have to use to get in/out of a parking garage isn't very sensitive, even for an original RFID card. I can hold the original RFID card about 3/4 above the reader to get it to activate. These keyrings have a very small footprint and the buttons are very close together. You can only press one button at a time to activate a programmed button. Due to the size of the keychain, and the low sensitivity of the reader, I have to press the keychain flat on the reader THEN press the button. It's too awkward to use the keychain any other way for that reader. You really don't know if a reader you use lacks sensitivity or not until you actually try this keychain on it.In a nutshell, yes, they do work fine. But how you end up having to use it, when programmed, may vary from one reader to another, and may require some inconvenient arrangement of the keychain to make it work.

2Pcs RFID Keyfob Tag Token 5 RFID Cards in One, ID T5577 Chip (4) and IC 13.56MHz (1)This product comes in two configurations and I am reviewing the first one:1) 5 RFID Cards in One, ID T5577 Chip x 4 and IC 13.56MHz x 12) 5 RFID Cards in One, ID T5577 Chip x 1 and IC 13.56MHz x 4I will refer to the "ID" as LF and the IC as "HF" from here. The HF chip is always active. The LF chips are only active while you are holding the associated button.These cannot be self programmed you will need a suitable tool for programming them. I used a combination of Android phone with NFCTools, Flipper Zero and a Proxmark3 to review this item.The LF portion worked as expected and was easily programmable with the Flipper Zero and the Proxmark. See the T577 trace information in the photos. To read/program one of the LF cards you most hold a button when trying to read/write.For the HF testing I first attempted to read with NFCTools and it worked fine. I was able to program it as a standard NFC card.I am not a wiz at using Proxmark with HF cards, but as you can see in the photos it is identified as a possible Mifare Classic 1K. It didn't identify as changeable UID, but as you can see in the photos I was able to change it. I believe this is a gen2.The description wasn't really clear but it does appear that it has the functionality described. It has 4 125Khz T5577 and 1 13.56Mhz ISO14443A card all in one. About the same size a typical key fob.At the time of review these are selling 2/$15.99. If this is something you need it is a fabulous value at twice the cost.
