Before I got this, I was using a bunch of old keys and cards that were always getting lost or not working smoothly. After trying it out, it's a bit of a letdown—it seems like it could be great, but the reliability issues make it more frustrating than helpful. I wanted something to simplify my life, but this just adds another thing to worry about. Not worth the deal I thought I was getting.
- Pros: It seems super easy to reprogram for different things, and the plastic feels tough enough for daily use. I liked that it works with my sauna without any setup hassle.
- Cons: It doesn't always read right on the first try, which is annoying when I'm in a hurry. The one size thing seems like it should fit everything, but it's not as universal as I hoped, and it feels a bit cheap for the price.
