Hi! I have recently purchased a Lenovo USB Flash drive and I am all praises for it. It addresses my need for a portable disk drive to share my personal data from my laptop to home PC or just to store or backup for data protection. All gets done with a simple plugging of this flash drive and file drag-and-drop. I can even save my favorite pictures also in a totally non-hassled manner. Thanks to gadgets.in, got a good deal and satisfied with the performance of this flash drive. 512 MB is limited storage capacity but ease of use scores over this – I transfer data to my home PC and carry the much needed important data only on this flash drive.
