To The Point Transfers worked but at a fraction of baseline speeds. My Opinion I tested this USB 2.0 extender with the same USB drive and a 12 GB .log file using rsync. Only one USB port on the receiver side was active for all tests. Results: Baseline (direct to computer): 44.634 MB/s Direct extender connection (Sender → Receiver): 6.451 MB/s LAN connection: 6.278 MB/s Live streaming from a security camera showed noticeable static While the connection remained stable, the throughput drop was substantial — roughly 85% slower than direct connection. I suspect speeds would drop further if multiple USB devices were active on the receiver. Pro: Simple setup, plug-and-play Con: Significant speed reduction over extender Con: Video stream quality degraded Con: Not ideal for high-throughput or real-time applications Pro Tip If you need fast file transfers, use direct USB connections — this extender is better for low-speed peripherals. My Verdict I’d give this 3 out of 5 stars for reliable basic connectivity but disappointing transfer rates. Works fine for printers, keyboards, and low-data devices, but not for tasks needing high-speed or real-time performance. I hope this helps! Cheers, Straight Shooter

To start with, I bought this USB extender because it would work over my network switches. Yes it does as advertised but the manual only show you connecting the sender and receiver together in a point to point configuration. I tried it over my network despite the directions. It works perfectly. As far as speed goes I can not tell the difference between my HD camcorder being directly connected to the USB 2.0 port on my computer vs the extender's speed. Prior to using this extender I was using the AV Access USB Extender Over Cat5e/6 196 ft system. It is a good extender but I did not like the fact I had to run separate network cables to my control room. Your PC powers up the USB sender. Just plug in your devices and windows does the rest. I am using this on windows 7 pro.

Used this to connect my back lane camera to my KVM powered box and had one key concern of the USB 2 would cause drops and poor video results. By using a higher end quality 300Ft cable the results are completely up to par with no issues at all. The power adapter works fine and so far very happy. No tests for speeed were done nor were requiredd to keeep this review simple. Follow instructions and all should work fine most use. Usb Flash drive was also recognized and transfer rate is acceptable though being usb 2 not at premium or highher speeds thus loses a star.

Item claims it works "over lan unlimited extension". I found that it does work over a single layer 2 switch, but once it went up to my layer 3 switch, it stopped working. Also, once the sender side is disconnected, the receiver side starts sending so much traffic it actually took down my network. Super easy to see, as soon as I unplugged the sender side, my wife immediately asked if the internet was down :D After giving up on this, I started using usbip which is free and does not crash my network.

It worked for a while then it would disconnect reconnect on and off after sometime it would stop and stay connected, then one day it said nope not going to connect they just wont talk to each other, changed cables and nothing. Why is it so hard to find a decent extender P.S. it dont work over a gig LAN
