A Wonderful, Spooky Little Gadget
Every once in a while something comes along that gives me a chill when I think of its ramifications. This is such an object. It functions well, is so small and light you don’t even know it’s in your pocket. For those who don’t know, it basically snatches rfid codes (the kind the fob on your keychain sends to your apartment lock) and can copy them to blank fobs that can be purchased on Amazon. This can save you the Lost Key Fee your building manager will charge for replacing your lost fob, which is good, but it can also be used on the sly to steal your fob, and you may never even know it happened. It’s fun, fascinating and has multiple uses. It’s attractive and seems well made. If you’re in the market, this is a great deal from this seller.

Great little device that works as advertised.
Great little device for cloning RFID tags for building entrance entry. Updating the firmware is painless if you have the required know how. I have a proxmark3 easy and have set up ProxSpace on Windows 10 to update it and used that as a base for setting up the Chameleon environment to update the firmware of the Chameleon. This device is for those that are reasonably computer savvy.

Know the Game
Well made still working 2 months on. Learning curve is steep. Will need sometime to figure it out if you're not familiar with process. If on the other hand you know what you're doing, this is a very nice piece of hardware that can ride hard in a pocket full of change and hardware and do the job flawlessly when you need it to

Good product
Good product. Genuine quality. It is probably OEM, so you'll get only the device without a strap or anything else. It comes with pre-installed dummy cards in slots 1-3 and a discharged battery. My second buy here. No issues.

HF works great, LF doesn’t work at all.
It worked with HF cards very well. However it didn’t work with LF cards at all even though it advertises it can. I never got it to read a single LF 125khz card. If it could do that, then it would have been a useful device to consolidate all my cards into one.
