Readable RFID Touch Memory Key

Before I got these, I was always fumbling with my old cards and had a few close calls with lockouts at work. Now, after using them for a couple of months, things are smoother, but not perfect. They do the job for basic copying, but compared to other options I've seen, they feel a bit cheap. I appreciate the convenience, but I'm skeptical about their long-term durability. Overall, they're okay for the price, but I expected a bit more sturdiness.
- Pros: I found these keys incredibly easy to use for copying my access cards without any fuss. The process was straightforward, and having five keys means I never have to worry about being locked out again. They work seamlessly with my existing system, making security feel more reliable.
- Cons: As it seemed to me, the keys are a bit flimsy and might not hold up well over time. I had some trouble getting them to read properly on the first try, which was frustrating. Also, the lack of clear instructions made it a bit confusing for someone like me who's not tech-savvy.
