I have bought a number of these over the years. This is because they always work perfectly but just as important, once you clip them onto your keyring they will never part company with the keyring. There is a strong, sturdy hole at the end of the memory stick that will not break off (as it does with so may other memory sticks). I strongly recommend this device as it is physically robust & does the job perfectly. I have 6 of these devices & the 2 directors of my company instantly instructed me to obtain the same device for them, as soon as they saw how robust my memory stick was.
