The case easily compares to other much more expensive units -- and I did PLENTY of shopping around before finally ordering this one, too!

I bought this as a gift for my wife, as she was not very happy with the cheap little base-mount chargers I had bought previously -- but I've heard nothing but praise from my wife for her new battery case. The case easily compares to other much more expensive units -- and I did PLENTY of shopping around before finally ordering this one, too! Most battery cases run from US $50 to $100 and up, and I've seen very little to indicate that there is any added value with the more expensive units. This BlackBox unit accepts a charge from the wall at 500 milliamps and also charges the phone at the same rate -- but when your phone is effectively always plugged in, it doesn't really matter that it's not as quick as Apple's 1 amp wall charger. The overall fit-and-finish is quite good, and the design is well thought out; it even stops charging for a brief moment when you plug it in, which causes the charging tone to chime on the phone, letting you know that you've successfully plugged it in.

The one and only complaint I can come up with (and the only reason I haven't bought one for my own iPhone as well) is that the charging port is micro-USB instead of a standard Apple docking port, which makes it incompatible with some accessories -- such as the iPod integration kit that I recently installed in my car -- but unfortunately, that seems to be par for the course, for these battery cases. As such, I can't really dock it any points for that, since there's nothing better out there... so I'd say five stars is about right.

The case is amazing--mostly because the battery in it is. It charges quickly and lasts seemingly forever. It works flawlessly, charging the phone first and then the battery in the case charges; the case battery is then used first, and it will last a full work-day of normal use. The case fits tightly, feels heavy and of good quality, fits tightly and protects well...in general, it's absolutely great. That said, the first case did have to be sent back because the connector inside the case was a loose fit in the plug on the phone and the phone beeped on and off and on and off every time it was even touched. However, no hassle--I called, printed the return label off the email I got, dropped the case at FedEx and the new case arrived in 24 hours, FREE. The product is great and Amazon's service is stellar.

This case fit well and charged the battery effectively. This is a good backup battery solution for the price. Recommended.

It is a very good product, it basically doubles to triples the battery. The only issue is that the materials it is made with aren't very strong so the case looks worn fast.

I bought this for my mom for Christmas. She has so much stuff always running on her iphone and talks a lot as a Realtor. She usually has to charge her iphone by 3pm or so. With this she says she never has to worry about the phone lasting the complete day. I guess she dropped her phone with this on int and the charging pin broke. She bought another last week because she said she couldn't "live without it". I ended up buying one for myself last week. I love it myself. It does add a good amount of weight to the phone, but is still a great device.
