UGREEN USB KVM Switch Selector USB 2.0 Splitter 2 Computers Sharing 4 USB Devices 2 In 4 Out Switcher Box Hub for Mouse, Keyboard, Scanner, Printer, One-Button Switch, 2 Pack USB A to A Cable 1.5M

I used to switch the cables when im useing the keyboard and mouse between ps5 and my laptop , this thing was so helpful and u can connect hard drive and use it with both with out any issues

Given me the comfort and convenience of not switching my USB by pulling and plugging it to my other laptop. The only thing is not and will not work is placing the EXTERNAL Hard drive on it. Maybe it will take time? I just pull it out as I was waiting so long it won't recognize. Plus it can / might potentially harm your EXT hard drive, i don't know. Long USB cables was provided which is very well-thought. 4 USB slot to be shared of which is more than enough. Maybe speaker or power source? Satisfaction guaranteed!

Very happy so far. It’s exactly what I needed. To be able to switch between two PCs sharing same screen. Easy to install. Fast switching.Hope it lasts for long. Then it’s a five star.

I use this USB switch to alternate the mic source for (steelseries arctis pro with gamedac) between PC and PS4. The gameDAC has 2 outputs: USB (to PC) and optical (PS4), but the the mic-USB input is from 1 source. So, using this switch has done a great job to give me the option to manually switch between the PC and the PS4 mic, "with affordable price and high quality"Thanks UGREEN

Using it to switch mouse and keyboard between 2 PCs.Plug the device into each PC using provided 1.5m cables and plug usb peripherals into the device. Press the button on device to alternate PCs.You will need to buy a separate power adapter to plug in high powered devices like hard drives. The box mentions the connector for input power is 5V micro USB.The USB cables that connect to each PC are USB A to A. The manual mentions not to use longer than 1.8m cables but longer cables should work fine for low powered devices.Update 07/2023:Since my review I've run into a couple of issues with this device:1. If you plug in a really slow USB device, every other device plugged in will also lag and become unresponsive. For example when transferring files from one of those old sandisk usb/micro usb flash drives.2. There tends to be frequent and unexplained input cutouts even when all you have plugged in are a wired mouse and usb keyboard and you're using just the keyboard. This is most noticeable when playing racing games and the keyboard decides to cut off right when you're flying towards a corner at breakneck speeds and completely lose the ability to turn and brake and smash into the !#^@#!^& barrier!!!As such I only plug a keyboard into this when I'm doing a lot of back and forth between 2 PCs. Too bad it's not plug in and forget.

This is good when you are using two systems for work purposes only.It switches Input quite quick. When it comes to the transfer speed in/out of a pen drive / external hard disk I wouldnt recommend trying to copy large files cos it is very slow (usb 2.0)While gaming, the input lag is noticible for a seasoned gamer. Wish they could've fixed this somehow.Overall, I would recommend this for using peripherals for work /official purposes. Bad for gaming. Bad for file transfer.3 star cos I am more of a gamer

Working as expected. No problem at all

I had two laptops at home to switch between work and gaming. Just had both laptops plugged into the monitor with auto detect.Just by one press of a button I swap my keyboard, mouse and headset from one laptop to the other.Works amazingly!
