Review: Ideal Business Setup - No issues or hassles. The directions had good pictures to follow along. I use this for business (no gaming) for zoom meetings, lots of open tabs, and six monitors while having the flexibility of a laptop. The reviews here on desertcart were a little intimidating, however I found the installation of this eGPU and video card to be straightforward plug-n-play and the product to be excellent as advertised. It was easy enough to do myself without needing the manufacturer's support desk. I added 64Gb RAM to my laptop and a Radeon R7 350 HD7750 4GB to this eGPUex. The internet port and 4 usb ports on this eGPUex model eliminated the need for a separate dock to have just one usb thunderbolt cord to my laptop. To have a clean desk, I used a simple under desk laptop mount. I also used a pc under desk mount. I combined two monitor stands for three monitors each on a single extended pole. I added a reinforcement plate for my standup desk for the mount which gives good stability. I used adhesive clips and adhesive cable ties to manage all the cables underneath my desk. I also got a pebbles sound speakers so I wouldn't need a headset and Bluetooth for mouse, keyboard to not need a docking station and reduce the number of wires.
Review: Quality product - Works as advertised with no issues.

Works as advertised with no issues.

### ⭐ More unreliable over time $700 on 2 units wasted.
*by A***L on January 2, 2024*

--new review-- These units have proven to be incredibly incompatible with many machine types. I have found them to be unreliable with multiple windows machines, linux machines and especially any machines running the newer USB4 / TB4 interfaces. You might get them working if you put them in a chain of 750ex > TB3 Hub > Computer. As such i cannot recommend these units at all. Look for something else. --old review-- I have two 750exe connected to two utterly different computers types (one a dell XPS and one a Surface) On both setups the USB has proved to be unreliable - causing mouse freezes for both wireless and wired mouse. I should note for me this only affects mice and keyboards connected by some other USB hub (USB2 or 3) or device (like a KVM) so if you are the type to keep your mice / keyboard plugged into you monitor do not connect this to the USB ports on the breakaway but to another USB C port on your PC. When the USB hub issues it also causes latency spikes on the built-in ethernet adapter too. If you plug devices directly into the onboard hub it may be ok. I would give the 750 5/5 star, but the 750ex only 3 out of 5 due to this issue. i would say sa
