Ex Input:
These were the first pair of underwear that I can remember that I've been dissatisfied with. For underwear, my expectations are simple- fit and sustained comfort. These provided neither. They are too tight where they should be loose and loose where they should be tight. Not a good choice for me.

Ex Output:
Tight where they should be loose, loose where they should be tight

Ex Input:
I have a PS4 w./ the VR headset and an external hard drive so I'm OUT of USB ports. This product seemed perfect - no wires, no messiness - turn 2 ports into 4. When you plug it in, it doesn't sit flush on the PS4, it rocks back and forth pivoting on the Y axis. First time I powered up, the HD was dead. I shut down, pushed in the left side of the unit so the right side "stuck out" (looks really weird) and the HD powered up, but wasn't being read. Other reviewers are correct. This isn't a good product. I gave it a 2 star because the design (in theory) is PERFECT.

Ex Output:
Doesn't sit "clean" on PS4, leads to connection issues.
