Bought 5 — kept 1, gifted 4!
I bought this after seeing that hidden camera incident at the NJ beach park — freaked me out. Loved the price and how it fits in my wallet. I kept one and gifted the other four to friends and family.

Love it!
Heard someone at my gym talking about hidden cameras being found elsewhere, so I bought one. It’s small, simple, and actually picks up the reflections clearly. I ordered some more to give to the girls at my gym.

Highly recommend
I’m on business trips almost every month, staying in different hotels and Airbnbs, so I wanted something simple I could rely on. This card is perfect — it lives in my wallet, takes two seconds to use with my phone, and gives me peace of mind whenever I check a room.

Customer Reviews
I wanted to leave a detailed review because I actually tested this card myself with my spare phone. I pointed it toward my old phone’s front camera, and you can clearly see the small red reflection through the viewing lens — exactly what a hidden camera detector is supposed to show. It works the same way as other, more expensive detectors, just in a compact, wallet-sized form. It’s light, sturdy, and slips right into my wallet beside my cards. No batteries, no app, no setup — just point and check. I also appreciate the simple red design; it feels sleek and discreet.
Pros:
affordable, easy to use, portable, and works exactly as described.
Cons:
none, really — maybe a small protective sleeve or mini guide would make it perfect.
FYI: for anyone new to hidden camera detectors, the reflections you’ll see are usually tiny — that’s totally normal.
It depends on the size of the camera lens, so don’t expect a big flashing light.
This card does exactly what professional detectors do in the same principle — it’s just way more convenient and affordable.
Overall, 10/10 for practicality and peace of mind. I tested it, it works, and now it stays in my wallet whenever I travel or use public spaces.
Super easy to use with my phone camera and the red design looks pretty sleek. It fits right next to my credit cards so I don’t even notice it’s there most of the time. I’d definitely recommend this to others.
For something so small, it’s surprisingly useful. No batteries or apps to worry about, just hold it up and check. Great little tool for solo travel. Happy I found this when I did.
Really happy with this card. It lives in my wallet and I use it whenever I check into a new hotel or Airbnb. Simple, light, and it does exactly what it says. Honestly, I feel a lot safer carrying this now.
Got a pack to share with my sisters and we all keep one in our wallets now. It’s affordable, practical, and gives us peace of mind in public changing rooms and gyms. It turned out better than I expected.
