the connection is constantly broken

Always connection disconnected or not working as expected.

One reviewer stated it lost connection when cable was moved

Very helpful with my used a hub for many hard drive connections

Was trying to use this as a way to switch between three different audio devices for work teleconferencing; unfortunately it randomly drops the connection to my wired headset, so it's just not useful for anything more than about 30 minutes.

I have 4 usb drives plugged into it but is constantly losing the connection and reconnecting

The warning in the product description is as follows:"For a stable connection, any device connected to the 4-Port

When it plugged in, I lost my Internet connection from my home wireless router.

Plugged my phone into my pc, worked fine instant connection

Secure connections, nice light to let you know when power is on.

n’t lose the connection while still getting the benefits of spending extra $$ to get an ergonomic keyboard.

In that year I unplugged and plugged it back in roughly 2000 times, until finally the connections went bad

The adapter constantly loses its connection

Without that, I can't use my 15 foot USB extension connected to this, and then to my mouse because the combined length exceeds the 15-foot limit for USB 2.0 through a passive connection.

When more of one port is used at the same time, errors occur, the connection fails, etc.

This one loses connection without that happening

Connection is loose at times

Work perfectly as a hub, connection is strong and not loose, please make sure to buy their other version of this product (the one with the power adapter) if you’re planning on using a Hard Drive or Solid State Drive on either of the 4 open ports.

I especially like that I can turn each connection on or off.

The connection is super slow and the mouse is unusable when it's plugged into the extender

If you are constantly plugging and unplugging USB ports into your laptop, eventually the port on your devices will become loose and the connections will not be reliable.

Multiple connection is great

Works as I expected it to, fast connections, but I must say the switches feel kinda poorly constructed and may not have a long lifespan

Faster connection, no lag

Does what I want, however, it is not a good connection for things like an external hard drive

While it does work about half of the time, the USB connections are too tight to plug anything in half of the time, and the other half where you can plug something in, the connection is way too loose and you can super easily nudge it out of place which is extremely unfortunate when you're trying to connect it to a microphone (had my computer crash during an important call due to this).All in all I would suggest looking at a different USB extension as this just doesn't do its job right.

Good, firm connections

An inexpesive solution to not having enough SATA 6 or usb 3.0 connections.

Connection between the plug and my laptop is secure and no problems with accidentally pulling it out

Awesome product, looks and works great but the problem I have with it is that when I use my PlayStation platinum headset, something in this device disrupts the connection to my usb

Like the sub hub with on-off buttons but loses connection for no reason

It works, but if you bump it or move anything nearby the devices will sometimes lose their connection.

The current connection will interrupt and you will have to start over.

when I the mouse and keyboard connected to the usb hub they lag and are do not have a consistent connection.

Works great, fast connection and the shut off buttons are a nice luxury.

All storage devices connected to this give I/O error.

n’t work at all

It works by powering to all ports; but DON’T touch ANY of the individual ‘power’ buttons as this wreaks havoc and is nothing more than a worthless gimmick

n’t had mine long but works fantastically.

n’t clear that you have to push a button by each port you want to work

n’t lose the connection while still getting the benefits of spending extra $$ to get an ergonomic keyboard.

n’t have concerns about it breaking any time soon.

Very useful I like it.
