Decent Shoes with Misleading Description (Not Leather)
Size: 12 Wide, Color: Black, Size: 12 Wide, Color: Black
I only look for leather when I’m purchasing dress shoes. Under the description “details” on this item it lists the shoe as leather upper and inner lining. A photo shows “genuine Napa leather lining”. If you keep reading (which I have now that I’ve received the shoes) it shows “faux leather” in the small print and that is not “leather”. I run a small leather business and this irks me because it’s clearly false advertising. The details also show the product is made in Brazil but when they arrived today, the shoe tag shows “Made in China” and “Man Made upper and lower”. I don’t hate the shoes. They look nice. What I know is they won’t hold up over time like leather, which is why the description should be accurate and not misleading.

Great piece of equipment. Worked for mouse, hard drive, and digital camera all into a laptop.
Works great. I used to plug in a mouse, an external hard drive, and an overhead Nikon digital camera for historic digitization of documents and books. It small and compatible and there were no connection or power problems. It feels well built and sturdy and the cord connection to the device is strong and flexible.

Great for retro emulation!
Got this for a retro emulation setup. Worked great. No issues whatsoever. Works on apple as well. Its a basic usb hub, but doesn't feel cheap. Got it on sale, which made it even better!
