The Mophie is the first stress reliever for Iphone. It removes the concern of a dead battery so you are free to use your phone without the fear of "will I make it through the day?"
We have owned over (7) 1G Mophie's in our office, so we have really put them to the test.
Below is my review of the 3G Mophie so far.
THE PROS:
1. They add additional protection and can take a drop from 4 feet pretty well.
2. The extra battery life rivals ANY product on the market
3. The non skid surface helps accidental iPhone dropping
4. You can recharge your friends dead iPhone (happens A LOT)
5. You are the only one with a charged phone when its 10pm
6. The added weight is minimal and well worth it.
7. Nice snug fit and sleek look
8. You can now sync your phone with a mini-usb cable!
(because the bottom is now mini-usb and not iphone cable, this is huge because how many times have you forgotten your cable, and now you can use the same one from a portable hard drive, camera, etc!)
THE CONS:
1. The non slip rubber does come off and the Mophie starts looking kinda sad (thats on the 1G, will update if the 3G stays the same) (UPDATE: RUBBER FELL OFF ALL 3 OF THE NEW ONES TOO, COME ON MOPHIE GUYS, THATS RIDICULOUS, GET BETTER GLUE ALREADY)
2. The same benefit in #8 above is a curse if you only have your iphone cable. Now you would have to carry the mini-usb too..
3. Everyone will want to use your Mophie to charge their phone. (no joke, this becomes almost annoying)
4. The side rubber came off on one out of 7 of our mophies (1G), but we never contacted the company, so im sure they would have done something about that. CONTACTING MOPHIE ABOUT RUBBER, WILL UPDATE...
5. Say goodbye to cases, your case will have to come off to put it in the mophie.
6. Its HARD to get the iphone out now vs the 1G. The 3G mophie you have to pretty much pinch and pull, where as before you could just slide it up from the bottom leveraging the space that DID exist. This will most likely be fixed in short order. (you can always just squish the volume button to pull it out, but I try not to man handle any buttons on the iPhone itself too frequently)
SUMMARY:
Even with its Cons, the Mophie STILL gets a 5 star rating (NOW DOWN TO 3 STAR BECAUSE OF SIDE RUBBER ISSUES). Once you get used to having it, its impossible to live without! Bare with its faults to have the best battery life you can image, or wait for something better, but I wouldn't hold your breath. (to prove just how far you will go, I actually shoved my 3G into my 1G mophie case till it finally died under the stress and thankfully, within days the 3G mophie came out)
SMALL NOTES TO THE PEOPLE AT MOPHIE:
1. The battery indicator on the back is now slightly "out" from the rest of the body, Mophie should fix this. While right now its not a problem, i can see this leading to wear on that button.
2. Offer other background colors than just the green.
3. FIX THE RUBBER ALREADY.. THIS IS NOW A HUGE DEAL
