Pros: I was pleasantly surprised to see it included a USB Type C to USB Type A adapter (no indication of this on the description or picture), which are $5-6 each by themselves. I was impressed that on 2 different computers it powered a mechanical 5400RPM laptop HDD solely via bus power, and the performance was nearly identical to plugging it directly into a SATA port (on the mechanical drive). On the 2 SSD drives I have used so far, they had faster I/O when plugged directly into a SATA port (as one would expect). I liked how the item fits into a spiral cutout of a foam rectangle... that doesn't really sound very appealing but I'm trying to say that I liked the packaging and will be keeping it and storing the adapter in it.

Cons: The cord could always be longer, it is only about 2 feet long. I guess if you're an optimist you could compare it to something like a Flash Drive which has no cord at all, and be grateful for those 2 feet.

Overall Review: I ran a few hundred GB through this so far, both read and write, while attached to several different 2.5 inch hard drives including an older mechanical one, and on several different computers, including an older non-networked Windows box running XP I added a USB 3 card into, and a newer MacBook Pro with only USB Type C ports, and I'm very pleased with the I/O rates. I can't believe the USB Type C to Type A adapter is not pictured and featured prominently in this listing, that's a huge selling point in my opinion and a pleasant surprise for me - I'm wincing as I think about how I've purchased 3 Type C to Type A adapters from Apple at $10 each, which is about what this item cost and it managed to include it for free and still profit.

Pros: Solid power bank. I really like how this looks. I bought a second one with the intent to take it apart but couldn't bear to do it. To me the design looks a lot like the iPhone 5/5s/SE phones, especially the white one. I have also purchased one for two different family members as a little surprise gift.

Cons: The white one was out of stock this afternoon so I had to buy a black one for my mom, and white is more in line with her personal style.

Overall Review: See my review of the white one https://www.newegg.com/Product/Product.aspx?Item=9SIA2J23UN4080 I am always apprehensive of "First from Asia" stuff but this was fulfilled by Newegg and shipped from California, USA.

Pros: I thought for sure that 10,500 mAh was going to be wrong, that seemed too high for the price if you look at other power banks on Newegg. In the manual it says it is enough juice to charge [5] iPhone 6 handsets or [1.5] iPad Air2 tablets, or [9] iPod 5th generation, which I also thought was doubtful. I don't have any of those devices, but here's what I did use to test: I let it charge until all 4 blue LEDs were solid and no longer flashing to indicate charging. Then I charged my iPhone SE from 4% to full. Then I used the 2.1A port to charge my iPad 2 from 3% to 87% charged before the PowerBiz-B100W was depleted. So based on that testing, I am pretty impressed. I don't know exactly how to measure mAh though. I would also like to note that I like the look! The design really looks like a white iPhone 5, and does not feel cheap (it is heavy, the insides must be filled to capacity with battery).

Cons: I don't know if I really have any, this thing was $9.99 all told, free shipping...

Overall Review: I think I am going to buy another one and take it apart to see if the battery has any markings on it to indicate the mAh.

Pros: Arrived in 2 business days, packed well enough to have made it intact.

Cons: None to report

Overall Review: Purchased July 7, 2016 for $16 plus $1 shipping

Pros: Cheap - $20 shipped to my door, good for older PCs without SATA channels that still have some life to them.

Cons: 1.00 Firmware is big on coasters. I have never ever has trouble before with an ASUS product until buying this.

Overall Review: http://dlsvr04.asus.com/pub/ASUS/ODD/DVD-RW/DRW-2014S1/DRW-2014S1_FW101.zip is a link to the firmware 1.01 for this drive - YOU NEED THIS

Pros: Allowed my customer to use a Parallel Print-Scan-Fax unit on his new COMPAQ which did not have a Parallel port onboard.

Cons: None to speak of.

Overall Review: When you install it it shows up as two things in device manager, both times you have to point it to the correct directory on the PC that corresponds to the chip on your card (don't just let Windows XP scan the entire disc). It said which chip on the sticker on the outside of the box so I didn't have to take it out to look at it.
