Pros: Decent feel for a dome switch keyboard, compact for a full size standard layout, cheap

Cons: Mouse feels cheap, wheel makes a raspy sound. I only got this for keyboard so not really a con for me, but if you game or spend a lot of time on the computer you'd probably want a better one. Edit: The lettering on the keys doesn't seem very durable. After 5 months of daily use several keys are almost completely worn off. Doesn't bother me, but if you care about that you might want to look elsewhere.

Pros: I got a 3 pack of these on sale. They seem to work fine, decent price, come with an adapter

Cons: Not very fast, measured write speeds 10 MB/s in cameras that get 30 MB/s with other UHS-1 cards.

Overall Review: If you aren't worried about speed, or have an older device that doesn't support UHS, these are a good deal. Otherwise, I'd look elsewhere

Pros: Both the card reader and disk interface work fine so far. I've used it to re-purpose some old 3.5" spinning drives for backups. Crystalmark showed 100MB/s sequential read and write, which is as fast as those disks were going directly to SATA. UAS works out of the box with both Windows 10 and Linux. U3 SD cards also perform as expected. Having the card readers and hub is a nice bonus if you have limited USB3 ports. There SD and micro SD slots are separate card readers, so you can use two cards at once, unlike some multi-adapters where the two slots are wired to the same physical interface.

Cons: The cord is a bit short (under 3 feet) to comfortably have the device on a desk with the computer on the floor. Un-mounting a SATA disk in windows is kind of awkward, since "safely remove" only lets you eject the entire device, and as far as I can tell you have to power the device off and on to get it back. This is probably mostly down to how windows handles composite devices, but it makes the hub less useful for keyboard, mouse or network plugged into the hub. You can eject SD cards individually using right click -> "eject" like normal.

Overall Review: I actually ordered a different product (with just the drive bay) so I was surprised when it showed up with card readers and a USB 3 hub. The seller eventually sent an explanation that was "due to the upgrade and maintenance of our backstage", and I have no complaint at all about a free upgrade on an already well priced product. Under linux, the device shows up as a GenesysLogic hub , ASMT ASM105x SATA interface and two generic USB card readers. The plug on the device is a USB3 B -Type, like used on printers.

Pros: Works. Crystalmark reported 90 MB/s sequential read, 70 MB/s write, probably limited by the cards. Seems fine.

Cons: Feels a bit cheaply made, but it was cheap so that's not unexpected.

Overall Review: This device does not detect the SD lock switch on full sized SD cards: The slot isn't physically deep enough for this to be possible. This means you can write to "locked" cards, which most people probably don't care about but could be a pro or con for some. The device manufacturer reported from USB is "Prolific Technology Inc.", product ID 2731

Pros: Worked out of the box on Windows 10 and Ubuntu 18.04.

Cons: None so far

Overall Review: I got this to display the NTSC-out from some digital cameras. It seems to do that fine. Detected as "MACROSILICON AV TO USB2.0" USB vendor 534d, product 0021. Worked in windows camera app, VLC, skype without installing any additional drivers. Also worked with VLC in Linux.

Pros: Works fine, > 500 MB/s sequential read and write in Crystalmark. No issues after 5 months.

Cons: None so far
