If the product arrives, I am satisfied; they seem to be of good quality, we need to test them to see if they work... But I recommend them, many thanks to the seller.

I just hope they work

Received the cards but haven't used them yet.

Arrived in 9 days, matches the description, works correctly.

Excellent product, worth the purchase. It arrived in Mexico in 8 days. I recommend the seller 100%. Quality and price for card blocking.

Very exclusive

It serves its purpose. It arrived in Peru normally.

My husband checked the transaction when paying for goods in the store. At two cash registers, the card was not recognized, and at the third register, the amount simply went through. The seller exclaimed, "I don't understand anything, what happened to the cash register?"

Good buy for the job in hand

Got it yesterday

Ok

Have bought them before, they work. but as i ave quite a few cards in my wallet, i am usin one on each side ot the "card stack". only one in the middle is not 100% safe.

Perfect

Looks good and works as described.

As described, highly recommended

Still need to test.
