Pros: Cheap.

Cons: USB 3.0 is an extension cable, it does not actually ADD a port. Only moves it from front to back. Card reader slots are NOT USB 3.0 but only USB 2.0. The specifications are not clear on this. I wish I would have read the other reviews first.

Pros: none

Cons: Item is a SINGLE speaker, not a pair. It is NOT a two-way speaker, but a DUAL CONE speaker. It DOES include a mounting ring adapter that is not discussed in the package or specifications.

Overall Review: I actually had to order a second speaker since shipping the first one back wasn't feasible. So now, the total cost of a PAIR of these are over $30 - you can buy much nicer speakers for less money.

Pros: Charging works as described.

Cons: The mini-USB charging port does not provide pass-though connectivity to the iPhone port. Slick finish coupled with beveled edges and rounded corners means that the case is difficult (though it is snag-free in pockets).

Overall Review: This battery case is very thin with rounded edges and a beveled back. Many would see these as strong positives. But, even though I usually keep my phone (with case on it) in a front pants pocket, this is not a plus for me. The Mophie case is so slick and beveled/rounded that I have a hard time literally gripping the case. It goes in the pocket well... but is really difficult to hold for any length of time. Also, I really dislike the wi-fi syncing on the iPhone and find the cable syncing to be much faster and more reliable. Coupled with the lack of pass through capability of the Mophie's case, the slick finish and difficulty to hold seemed to be a deal-breaker, and I ordered an alternate case from Newegg that works much better for me.

Pros: Inexpensive.

Cons: Not very durable. First SD card out of many I have ever owned to separate the case. Mushkin not very friendly to deal with IMHO.

Pros: Pretty good spec list.

Cons: Win 7 build locks up EVERY time when trying to update drivers. Have eliminated every variable other than mobo, sending it back. Board does not seem well constructed, very thin and flexes a lot under card/memory installation. Driver bundle CD installs a lot of junk.

Item arrived quickly and sufficiently packaged.
