Perfect
This device is very good it copied my key fobs the first time and was able to duplicate it onto the tabs that came with the kit. My community has a gated pool and several times I forgotten to take my fob but never my phone so I put the tab on the back of my phone and it works great. These individuals that claim it's difficult to operate obviously did not read the directions works great and is very simple to operate. ... show more

it's cheaply made and does not work.
This only worked twice, Now it stays yellow and never turns green which is necessary to make a copy. It is a cheap crappy product. Do not waste your money!

It Works!
Wasn't sure if this would would but it was so cheap it was worth finding out. Lo and behold this cheap piece of toy plastic works!! Easy to clone. This works in a large apartment complex. My building wanted to charge me $150 for a new key fob. No thanks, buy this instead and get 6 fobs for a fraction of the price. ... show more

Works great to copy fobs
Worked great. One button to read my existing condo access fob, then one button to copy the info to any of the included new fobs or “dots”. I put a dot on the dog leash. Now I won’t be locked out anymore when I walk the dog and forget to take my keys. Note: Your building management may not like it and may have rules against making copies. ... show more

Not horrible but not great
Does its job, but the fobs it comes with stop working after a couple months. Not a huge deal but definitely annoying.
