These LOOKED great - especially with our logo on them - but when it came to actually USING them, it was an entirely different story. The reason for our purchase was to provide clients with an easy way to deliver copy and/or images that made our BRAND look good. However, after one or two, uses, the component that you actually insert into your computer would collapse back inside the housing or jam and the button that was supposed to make it slide out was temperamental at best. This was true of each and every one of the bunch. Embarrassing to say the least. NOT what we would have expected from 4IMPRINT - one of our favorite vendors, by the way. A total WASTE of money!!!
