It seemed to me at the first attempt something cheap when it comes to the plastic of the housing, but this is perfectly adequate if you normally use them. He also has two mounting options for the everyday: The large ring at the end and in front of a small hole for a thin strap or something.
The speed I have not exactly been tested, but is according to my source in the useful range of 8 MB / s read and write 4MB / sec.
There is also a software for password protection, which can only load to match the serial number of the manufacturer's site needs.
The protection is used by a symbol that performs a password prompt if you want to enter the restricted area. Upon successful next to the symbol is only the protected content on the drive letter and icon leaves a switch back if necessary.
The proportion of the protected area can be changed only when formatting and do not put entirely on 100%, but without the password, you can only format it and assign a new empty then the stick, but not the normal way to the data.
I can not imagine that the protection can be circumvented in a roundabout way, perhaps through some operating system (have not tested) or the Data Recover After formatting, but safer than a normal stick this is definitely.
Because of the slightly cheap looking case and the speed only 4 stars.
