## Customer Reviews

### ⭐⭐⭐⭐⭐ USB LOCKS
*by  on Reviewed in the United Kingdom 24 February 2014*

Just what i needed, very durable and able to fit and secure usb's, need to be a bit delicate when using as the connector is very thin

### ⭐⭐⭐⭐⭐ Handy
*by  on Reviewed in the United Kingdom 17 July 2013*

As my laptop is almost on the road I ve found this product very useful. Extra protection. Good stuff. I am using continuously. Thx

### ⭐⭐⭐⭐ Do what they say
*by  on Reviewed in the United Kingdom 25 August 2021*

They work, very difficult to remove without the key and if the socket is slightly set back they are close to impossible without the key. The only issue is there are only 4 or 5 keys available and they are easy to obtain so any body determined to get into your system will not be stopped. Especially if premeditated.
