Pros: Nice little box; does what it's supposed to do. I agree with the other poster; these are some very bright L.E.D.s! Even though it will break the warranty I'm going to open it up and swap out the LED resistors to make them dimmer (I'm an Electronics Designer and do this stuff every day; not recommending this for the average user).

Cons: Nothing that can be done about it, and not an issue, but it can't sit flat with the cables sticking out the back. It's so small and light it gets lifted up. I'll use some "poster putty" to get it stuck down. Not marking any eggs off it; it's the nature of the beast...

Overall Review: Not sure what the other poster was talking about with the remote battery. This is a common thing with small remotes, and my unit came with the battery.

Pros: See below.

Cons: Bought this in on October 8, 2013 (Dec.1 2013 as I write this). Seemed to work okay sometimes with Win 7 x64, worse in WinXp x32. Sometimes things would be recognized, often times not. If they were, they were not recognized as USB 3.0 (I have a few things that are the new spec.). Now the thing is dead. Things plugged in get power but not recognized by system. So, at this point it's junk. BTW; I tried un-installing, re-installing the thing as well as running the latest drivers - nada.

Overall Review: As others have mentioned, if there is a ridge or rim around the opening for the slot where this card plugs in (usually the first slot on the MB) you won't be able to plug USB connectors in all the way. I found that with a small X-Acto knife you can cut the edge of the plastic back enough so that the connector plugs in all the way. Easier than modifying the computer chassis.

Pros: None.

Cons: I checked on the Lenovo website before making this purchase - thi ssystem is NOT able to be upgraded to Windows 10. Not a big deal if you don't care...

Pros: Look nicer than the photo.

Cons: None.

Overall Review: I bought these for my wife to go with a citrine ring and pendent previously purchased. These look great, are large and the stones are clear. I wouldn't hesitate to recommend these to anyone for themselves or a gift.

Pros: None.

Cons: I bought this thing some months ago. I tried it with a drive and it didn't work. I've tried this with a number of different drives. It will connect via USB, briefly. I tried copying files to the drive (1) installed in the DUET. It copied some files, then the system said it couldn't find the files, even though they showed up in Windows Explorer. Disconnecting, re-connecting did not help. I thought I'd try via eSATA; that doesn't work at all. I tested the port with another device and it works fine. This thing isn't worth the plastic it's made from. I really think Thermaltake should take some responsibility here; I looked on the internet and very few people have anything good to say about this thing. Don't waste your time or money.

Overall Review: Anyone want to buy a boat anchor, cheap?

Pros: Case is made of metal, slopes in the front. Spacing between connectors is enough that I haven't had any problem using all of them at the same time. A blue led comes on next to the socket when a data device* is plugged in. Power switch on the side of the unit turns it off without having to unplug the main USB. I have not done any extensive testing of throughput speeds; I have many devices in use and not interested in going through each case. I tried using the hub with microcontroller programmers from MIcrochip. It did not work. I'm not sure if this is the hub or the programmer. In my case it was a non-issue; the hub freed up all the other ports on the machine so I just used one of those. Overall, I am very happy with this unit and when on sale I will buy more of them. With all the phones, Bluetooth headphones, MP3 players, tablets I have it is worth it to just have on the counter for a charging station (and I have filled all 10 and not a had a problem charging anything).

Cons: See other thoughts.

Overall Review: Not really cons, but a couple of things I thought odd. When you use a data device the led on the connector comes on. But when you plug something in to charge it does not. If the thing being charged didn't have some indication that it was charging you may not think it is. The other thing is the supplied USB cable is the new 3.0 USB-B "SuperSpeed" type. Unclear to me what ramifications this may have down the road; just don't be surprised when you see it.
