Pros: I still love this case, but there is room for improvement.

Cons: When the cover of the case swings open, there is considerable force placed on the internal USB3 port connector. This resulted in the first broken MB connector pins that I can recall ever happening to me (bent yes, but never broken off). Extreme care needs to be taken to disconnect the USB3 cable from the MB BEFORE completely opening the case cover. Perhaps Lian-Li should include/develop some type of 20pin quick connect adapter and include it with the case? Otherwise a longer USB3 chassis cable should be used by Lian-Li instead, because this is a very common location for internal USB ports.

Pros: Small and Windows 8.1 automatically I stalled drivers.

Cons: Package was missing the 1x Power Cable, but did include the mounting screw! LOL

Pros: small

Cons: unreliable and inconsistent power levels

Overall Review: my case is well ventilated and my power supply is several inches from my CPU fan and immidiatly opposite a case fan. the Newegg power supply calculator suggests my system needs a 420-ish PSU, and yet I am sending this 600W PSU to Thermaltake for a 2nd time because it fails to provide enough power to my components - hard drives. if they can design and build a beefy SFX PSU with true 600W specs, they shouldn't manufacturer and market such a device.

Pros: delivered quickly, priced well and came with a zipper semi-solid case and had assorted ear sizes.

Cons: Sound wasn't as good as I was expecting (Beats/Apple's problem) more shallow than I had hoped for a newer generation BT headset. Stopped charging Nov 25, 2018 - 4 months after purchase.

Overall Review: now I wasted approx. $90 for headphones which don't work because they won't charge. If I had purchased the retail product I would have paid nearly double, but it would be covered by a more respectable warranty. This is not the first certified refurb I've purcased, but it is the first which went belly up before 6 months.

Pros: Sturdy. Great utility. Great design.

Cons: Shipping took a little longer than I expected, but well worth it in the end.

Overall Review: Going to look for a USB 3.0 and 3.1 equivalent now!

Pros: The layout seems great and the idea of a separate numeric keypad is wonderful. I love the addition t

Cons: the key mechanics and printed letters are not as durable as one would expect for such a high priced and high profile product. The after 18 months, several letters on the "home row" have worn away. More importantly, several keys have been acting erratically and either not working or have been getting stuck. This used to only happen when the batteries were low, but now it is happening more consistently and frequently to the point where I can no longer type without my cursor zooming around the page. With that said, I just got off the phone with MS Tech Support and discovered that the keyboard set has a 3 year warranty and they will be sending me a replacement asap. Phew! :) Lastly, the software/utility that comes as part of the keyboard and mouse to customize it's settings is pretty useless and after every new pc build or upgrade, I need to uninstall the software in order to have them perform consistently between Windows and "RT" apps.

Overall Review: In order to "make this keyboard and mouse" ergonomic, the use MUST make certain that their desk is at a proper height. If the user's desk is too low, the keyboard and especially mouse terrible and painful to use -- this primarily a problem for the mouse because you hold it "sideways" when compared the a typical mouse. If the desk is too low, your arm/hand rests on your wrist bone - ouch! If you can, raise your desk or adjust your chairs height, the problem goes away and the ergonomics are back to great.

I really have to say that this internal USB riser works amazingly well inside my pc! Sturdy, sits tightly in the socket and conveniently has a USBfacing either direction to make sure it works for every motherboard and case!! This unit 'passed the test' and I'm now going to order more!
