... And yet discreet: 4.5 cm long and 1 cm wide and about 4mm thick ending in a ring peit very convenient. Metallic, it appears solid. Tested, without being one of the fastest for USB3, it behaves honorably and within the capacity / price ratio, quite satisfactory. I hope that reliability will be at the appointment. I already had the opportunity to test in the same 32 GB with a friend, this is why I chose this 64GB model. I use it as a boot key to troubleshoot computers (with different systems installed on it): perfectly recognized, it poses no problem so far. I recommend.
