I have only two issues:
1. The manner in which the hinge top clips to the phone will eventually wear to the point of no longer locking onto the phone. It uses a small lip that rides over the top edge of the phone. The lip is plastic so with time, will eventually wear away. I've owned this case for about 3 months now and the "grip" of this lip is beginning to loosen.
2. I cannot use the ZAGG InvisibleSHIELD with this case; it loosens at the edge and within 3 days peeled off.
In hindsight I should have waited for the Mophie Juice Pack case. I had one of these for my iPhone 3GS and really liked it. I was able to use the ZAGG InvisibleSHIELD with the Mophie case. My only issue with that case was after 1 year of constant use (and a few drops) the top corner of the case began to crack. The case's wall thickness gets quite thin in the corners so it's no real surprise. Perhaps they've improved in the iPhone 4 version.
The aforementioned lip on the case broke after only 9 months. MiLi would replace it under warranty but I had to pay for shipping to Shenzhen China! It would cost me just as much to buy another case so I bought a Mophie instead. Mophie Juice Pack Air Case and Rechargeable Battery (Black, Verizon and AT&T iPhone 4)
I only bought the MiLi because they were first to market and I needed it for frequent overseas trips. No issues with the iPhone 4 Mophie, also no issues with the 2.5 year old iPhone 3g Mophie case.
Lesson learned: wait for Mophie, they make a better product.
Calls and emails to the company have gone unanswered.
Don't buy this, there are much better alternatives
Easy to use.
Protects back and sides of phone from scratches.
More durable feeling.
Very Sleek look.
CON: You have to take the iPhone out of the MiLi device to use existing cables, docks, and holders for the iPhone.
I got this item because I use a golf gps app that can be harsh on the battery; although, I could usually make it through a round without any battery problems I didn't want to ever have to worry about battery problems on the course. I finished charging it yesterday morning (26 hrs ago) and played 18 holes of golf with the gps on the entire round (about 3.5 hrs) and this morning I still have 3 LED power indicator lights on the MiLi meaning that the MiLi has between 50-75% power left, and my phone still has a full charge. I would normally be down to 40ish % battery by now. It should be noted that GPS apps are by far the most taxing on the battery. Far harder on the battery than playing video and audio so using the GPS was a good test.
I think the MiLi recharges the iPhone periodically to keep the iPhone battery full, rather than using all of the battery in one source, then moving to the next source.
One con I kept hearing about this device was its bulkiness. I personally like the extra bulkiness it adds to the phone. I think it gives the phone a little more of a rugged and durable feel. (Although it doesn't make it any more durable, just feels that way.) I always thought the phone felt a little too fragile like I was holding a sheet of glass.
One downside I can see to the bulkiness is if you have any holders designed for the iPhone, such as in your car so you can easily change music or use iPhone for gps. Also, if you have any docks for the iPhone, it won't fit anymore.Read more ›
