125khz RFID Reader Writer,Handheld RFID Copier,RFID Reader for 125khz Id and Hid Cards (with 5pcs T5577 Key Fob and 5pcs T5577 RFID Cards)

I don't care what some other reviews have said, this thing has saved me a ton! I was able to make duplicate access fobs for my family to get in the gate, id card access for my friends pool, and other uses. I was skeptical, but surprised how many successful times I've had with it

A couple didn’t work but I allegedly made 4 copies off of my original key absolutely no problem.

Worked once to copy a fob and will not work again. Cheap, useless plastic. Not worth the buy

Yes, it’s terribly cheap-looking. It’s design is so simplistic it seems counterintuitive to use it for tech. It’s a bit of a crap shoot, too - the first one I got did not work at all. But the second one was the real deal. Reads and writes both cards and fobs accurately and reliably. I persisted because the alternative was to pay $120 to the HOA for another keycard to access the dumpster, and I’m so glad I did. Someone else posted this detail too: the one that works beeps 3 times when you turn it on. The first defective one I got only beeped twice, so I’m confirming that this may be a good way to tell if you’ve got a dud. In the end, it was well worth the hassle - not ideal, but worth the money I saved.

I was skeptical that the device would work, but it proved me wrong. I used all five of the fob keys. It was really easy to copy the keys; I just followed the instructions.

Regardless of what the other reviews said, this reader works great! I was able to copy some keys and save myself $200 for the replacement charge.

Super fast working and easy to use. Highly recommend

I have fobs that are 125khz passive unencrypted. I have been able to copy them with instafobs at home depot and lowes. I decided to get this because I can get multiple copies made at home for less than I'd pay at the store for one. Or so I thought. I got it and tried it immediately. It did not read my fob at all.I tried new batteries as youtube videos said it was sensitive to voltage. I even checked the voltage on the batteries, 1.59v each, or 3.18v where this needs a minimum of 3v. So not the problem.I decided to check and see if it could read the fobs and cards that came with it, even though they are blank. It read the fobs, but not the cards.I started an amazon return thinking it was defective and got another one sent to me. I tried this one out and it has the exact same problem.Do not buy this. It does not work. There are videos on youtube about people with the same unit and the same problem.
