I purchased this when I first bought my S4 due to good results with my iPhone. I will separate this into pros and cons. There are several large flaws in this product that is not stated on the box! This was a new unit being used with a factory battery on a new phone. These observations are after 2 weeks of use. There are several important cons so please read my recommendations before purchasing.

Pro's
-Adds to the time you can go between charges
-Has a nice rubberized feel
-Doubles as a case
-Ability to turn charging on and off

Cons
-Blocks the use of NFC not stated on packaging
-Blocks the use of S Beam also not on packaging
-Consistently lost 2-5 db of signal strength despite their claims of no signal loss. This made the difference between dropping calls and having data coverage where signal was weak and having to remove it to make the call.
-With the Juicebox installed the phone will not go into dock mode due to the lack of pins that the Samsung micro usb cable use on their docks
-Without the Juicebox installed the charge rate with stock charger and usb cable is 1200maH with it installed and fully charged it only passed though 740mAh with it on or off!
-You theoretically add 2200mAh but loose around 10+% due to the inefficiency of charging circuitry plus they also only recommend turning it on when the factory charge gets down to 20%. I don't want to have to watch my level all day. All that bulk only gets you 1980mAh battery at absolute best!

This was a great idea but it does unfortunately have a few bugs to be worked out before it's worth the price.
The case blocks the use of NFC and S Beam features of the phone. You must remove the case before those features work.
About 20% of the time the case only charges my phone for about 5 minutes then acts depleted. (This is when the light indicator shows that the Mophie Juice Pack has a full charge before switching it on to charge my Galaxy S4.) When I plug the Juice Pack in to the charger for as little as a couple minutes it miraculously has a full charge indicator again, at which point I can turn it back on and it charges my phone to 70-80%.
Also the top part of the Juice Pack regularly pops off in my pocket or backpack. And the one time I dropped it that same top part popped off leaving that part of my phone unprotected from hitting the ground. Now I have a nice sized gouge in the top of my phone.

I still use the Juice Pack for the convenience of having a backup battery but I can't go anywhere without a charger just in case the Juice Pack decides not to work. And I'm constantly having to dig the top piece out of my pocket. I would have rather just bought a detached battery pack to carry in my pocket or backpack that I could just plug into my phone when needed and used a phone case that would stay together and actually protect my phone. Live and learn I guess.

The Mophie Juice Pack for the Galaxy S4 is a decent product but you should know what you're getting.

PROS:
-Nice matte black finish.
-Case feels smooth and sturdy.
-Adds a good amount of bulk to the case (If you like your phone slim this is obviously a con)

CONS:
-Battery has only given between 60-70% rather than the 80% that is advertised. This is with the stock battery, 4G turned off, wifi turned off, brightness turned all the way down, and power saver on. If you're looking for more than you're better off getting a separate battery altogether.
-NFC does not work with this case on.
-S-Beam does not work.
-Some report that the microphone quality goes down with this case on, but I have not had any problems.
-Very expensive!

Overall the Mophie Juice Pack does a good job if you need an extra boost to get you through the day and wouldn't mind shelling out some cash!

Charge is only about 50% longer. Works better as a case. Save yourself money and purchase less expensive competitor these guys must really be iPhone focused.

Thisis practically an unfinished product. It looks nice, and it guards your phone in case you drop it, yes. However, the reason you're spending $100 on this, is to be able to charge your phone on the go. Below I'll list out a few of the issues I've experienced.

1. Does not support docking, another user explains the poor circuitry much better than I could
2. Halves the charge rate, if you plug this in while yourphone is in it
3. (My experience) - freezes after turning it on. It will start recharging my phone while I'm out, and sometimes become completely unresponsive after a few minutes. The LEDs do not respond, and there is no change after switching it on and off. It simply stops charging my phone and becomes a useless brick that weighs my phone down and makes it significantly larger.
4. Charge - this is probably the most important thing, I'm lucky to ever even get 50% out of this. The charge rate is slow, and even then, you truly do not get a full 2200 mah charge out of this. It's a complete bait and switch from what they advertised. I just went on vacation and was struggling to keep my phone alive throughout the whole day. It's really annoying to have purchased this device, and have it not even able to do what it's advertised to do. This wasn't a cheap product.
