very poor quality
Size: 14, Color: Black
they are a peice of garbage, within about a month since i started wearing them the outer material started pealing off within two months the upper separated from the soles so i had to go to a shoemaker to sew them back together, within some few months the insoles completely wore out rendering the shoes unwearable, now mind you that i do not abuse shoes but use them in a normal office oriented enviorment, i will for sure not be buying these shoes again

4 USB-C ports, Quality Build, Value for non-KVM Users
Style: 8-in-1
If you’re looking at this product, it probably means you are curious if this is better than the cheaper generic brand hubs and don’t really want/need a full KVM. It most definitely is, premium quality, has external power for powering any type of higher power draw usb device you may be using. The thing that sold me was that this was the cheapest non kvm hub with 4 USB-C ports (instead of 2 or 3) in addition to all the extra USB-A ports it has. I thought about going the USB-C pcie expansion card route but truthfully I do have one or two usb devices that have always had weird behavior on just motherboard power, and shocker I know right, no issues on my externally powered hub/splitter, total game changer. Do yourself a favor and eliminate the hastle and buy the brand you can trust won’t end up being junk that you want to send back!

Perfect for a midi keyboard music setup
Style: 8-in-1
I bought this to setup a midi keyboard for the worship team. I connect a couple ipads and the keyboard and it works great. It powers all the devices, has good length for the power cord and just works as intended. What else is there to say. It's a good product.
