Customers say
Customers find the signal blocker works well with keys inside and provides excellent value for money, with one noting it performs as well as more expensive alternatives. Moreover, the product is well-made, blocks signals effectively, and keeps vehicles safe from thieves. Additionally, customers appreciate that it’s large enough to accommodate most car keys and fobs, though some mention it’s too large to fit easily in a pocket. However, there are mixed experiences with car unlock functionality, with some customers reporting successful door operation while others say their cars wouldn’t open.
