This is my first ever review because I feel like way too many people write unhelpful reviews that dont really state, describe, or test the actual item before reviewing it. I have had an rfid lock electromagnet lock on my door for the past 2 and half years running a controller like this one all day everyday (they are all the same just re-branded by different companies). At the time of my original purchase, there were many reviews stating they last a matter of weeks/month or two. I can make an educated guess that these people have wired it incorrectly which I mean no disrespect by as it is a huge PITA. It took me an hour or two looking at the wiring instructions that came with the controller, magnet, and rfid keypad (which were all a little different) as well as some online. So, if you are willing to go through the headache of figuring out the correct wiring, then I can definitely recommend it. I should also add that I recently purchased a second one (which has been in use for about 3 months) and it was super easy to wire since I already went through the original process. Overall, do your research, hope you dont get a defective controller (mine definitely are not but this is quite cheap Chinese product so there will be the occasional lemon), and be patient.Update: After 4 years and 3 months, it has died. Rip.
