These are ideal for extending hard-to-reach USB ports, e.g. B. on the back of a computer case where access is restricted. The 1.5 foot length keeps ports accessible without adding excessive clutter. Speeds are excellent, there is no noticeable drop in transfer speeds when used with external USB drives compared to connecting directly to the motherboard USB 3 ports. The price is reasonable. Bring a few more than you think you'll need, they come in handy.
