Even the USB connector is made of plastic and it looks like it could easily break off
Unbiased Review, Amazon
8 July 2014
Summary: This product works but I didn't expect it to be made almost entirely of plastic. Even the USB connector is made of plastic and it looks like it could easily break off. I would have preferred the connector to be made of metal like most USB flash drives. I do not recommend this product.
Summary: Bottom line, these function, however the quality of the plastic and mechanism are marginal. I have an Ativa brand that I have used for years and it shows no wear or distress. If your needs are met with onsite occasional use, these may do, but I would not buy more since I use them often and quality matters.
