Pros: It offers both 1 amp and 2.1 amp ports for charging phones and tablets. Aluminum casing still feels solid after months of use and abuse. It's a reasonable size and weight for my application.

Cons: A couple times it seems like it actually drained the battery on the device I was trying to charge when the external battery was nearly dead. So I generally don't use it unless it's at least half charged.

Overall Review: I bought it specifically to use with my GoPro Hero 3 cameras and it has worked perfectly. Normally the GoPro (with addon battery backpac) would be dead in about an hour, with this battery pack I've been able to use the GoPro for 6+ hours straight dozens of times without any problems.

Pros: Works as expected once the BSOD issues were fixed.

Cons: It took me two full days of frustration to figure out that disabling Bluetooth and WiFi in BIOS would stop Windows from cashing constantly.

Overall Review: I've been building my own systems for about 10 years. I decided to switch from Intel to AMD for the multi-core/hyperthreading capabilities. This was the most challenging build I've ever done. Previously I did my research, ordered my parts, put them together, and everything just worked. This time when I installed Windows it wouldn't run for more than 5-10 minutes without crashing, typically with a BSOD. I tried various hardware and BIOS settings for the RAM, video card, and hard drive. I tried updating Windows and installing different versions, sometimes Windows would BSOD during an update or even BSOD during the initial installation. I was just about to return this motherboard because it appeared to be defective but by sheer luck I disabled WiFi and Bluetooth in the BIOS and suddenly everything just worked. I've been using the system for two days now with no crashing what-so-ever. I'll state this clearly for anyone who may have a similar issue, disabling Wi-Fi Controller and Bluetooth Controller in the BIOS fixed my BSOD issue. I'm not sure if the issue was caused by one or both of those settings, but since I don't need either of them and my system is working now I haven't been interested in changing either of them back to test it.

Pros: Burned all 10 discs with no problems on a Sony Optiarc burner at 2x. All have played flawlessly on the same drive and on a separate Blu-ray player.

Cons: None

Overall Review: I haven't tried them at 4x yet but I'm in no rush right now.
