Just what I needed
Color: Black
Never given!give 5 stars. But, this got it because exceeded what I was expecting.
Purchased because new computer slots were inconvenient and more new devices are using usb ports and having powered ports was essential. Have used for several months and keep finding more things needing it. It was more than I expected/needed at the time .But, was designed for growth I was not expecting. Getting excellent connections, speed, and reliability even though I’ve nearly doubled the devices I planned on using. To be clear the system I connected to is all about performance and top of the line hardware. I was a performance engineer in a previous position and am very picky with this system setup. I’ve tested the hardware several times tuning things and it’s never the bottleneck.
The original purchase was intended as a short term fix when I needed something yesterday and as stated b4 it has earned a place in my permanent setup.
Would buy again and would explore other offerings by manufacture.

Very useful USB hub
Color: Black
Works as described. This thing has more inputs than most will ever need. I thought it would be big and bulky but it doesn't take up much space at all. It's super lightweight, except for the power supply but even then, it's not that heavy. I'm currently using some of the USB 3.2 ports and 1 of the USB charging ports with zero issues and now I'm able to plug more devices without fear of my PC struggling to communicate with them all. It's a little pricey compared to other USB hubs but I feel it's totally worth it.

Super product.
Size: 12 Outlet, Size: 12 Outlet
Really happy with this strip. It mounts to the wall on the ends, which is MUCH better than attaching with hidden keyholes. Having a lighted switch above each outlet is very useful and saves both power and extends the life of components not in use. The cable retention on both ends is genius. Wish I had one of these years ago

Great power strip for my shop vac and miter saw!
Size: 12 Outlet
Works great in my garage! I currently have it mounted on the wall and have my shop vac and miter saw plugged in. It makes it incredibly easy to turn the master switch on and have my shop vac and miter saw turn on at the same time. When I’m not using the shop vac and miter saw combo, I shut off their individual switches and I’m free to use the other plugs so the individual switches for each outlet are very handy! It’s very durable as I have it mounted on the wall and has an adequate number of outlets for my work bench. The size is just right and it was very easy to mount. My only suggestion is to space the screw holes on the power strip so that it can be mounted between 2 standard wall studs 16 inches on center for unfinished wall mounting. The screw holes didn’t line up like this so I could only put screws on one side of it and I needed to improvise a way to secure the other side of the power strip to the next stud so it was as mounted securely and didn’t move as I plugged and unplugged things.
