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.
The card itself works fine and feels well made. Shipping took longer than I expected, which is the only reason I’m not giving five stars.
It works and I keep it with me, but the packaging felt pretty basic. Functionally it’s solid though.
Shipping took a long time and the card came with visible scratches. Maybe I just got unlucky, but it wasn’t a great first impression.
Bought this for my wife and she keeps it in her wallet now. She likes that it doesn’t rely on tech or charging.
