Don't let the other reviews sway you away from this accessory. I couldn't be happier. Let me address the concerns that you might have.

First and foremost, performance: I followed the directions and gave it a 12 hour charge before first use and then let it run all the way down before I recharged it the first few times I used it. I can easily go 2-3 days now without a charge, and that's with full brightness, wifi and bluetooth on all the time. Basically it does exactly what you'd expect, last several times longer than the original battery. Now let me address some concerns other reviewers had. This was my personal experience, which seems to differ from some other people who got this battery/case.

1) The weight. Some reviewers are complaining about how heavy this battery makes the phone. Of COURSE it's heavier. You're putting in a battery that's basically 3x the stock battery. So imagine three of those strapped on the back and thats about what it'll weigh. Mine weighs about 12 oz now.

2) Signal Loss I haven't noticed any signal loss at all. I'm still almost always connected to Verizon's 4G LTE, and have no trouble connecting to my home wifi.

3) The cuts of the case. The cuts on mine are all dead center and give a wide enough space at the top to connect even my fattest headphones.

4) Durability: Like someone else mentioned, it's no otter box, but It feels sturdy in my hand and I feel confident that it could handle a pretty substantial drop. The bevel also goes slightly above the face of the phone so you can set it face down without setting the screen directly in contact with the table or whatever.

This is a fantastic extended battery and case combination, although I've had some difficulties in testing it thoroughly. Simply put, the battery lasts too long for me test without interruption! --For one of my tests, I set my phone to 100% brightness, 100% volume, and loaded up a 10 hour YouTube video, set to play at full screen. With this 7500mAh battery, at the 8 hour mark, the YouTube video stopped inexplicably and the battery had only lost 35% of its charge. With the standard 2600mAh battery that came with my phone, the battery completely discharged by hour 7. The discharge rate of the Zero Lemon extended battery is very impressive. Also equally impressed that the battery did NOT become excessively warm during charge or discharge (a potential sign of poor workmanship).

This battery does add quite a lot of bulk and heft to the phone. The battery is almost too snug of a fit, as some of the paper covering the battery got damaged while wedging it into the battery tray. The case is very well made and precisely fits the contours of the phone, without being too difficult to remove or install. The case has a nice matte texture that gives a much surer grip than the slippery factory battery cover, all without hindering the ease of removing it from your pocket-- it won't catch. The grip is important as the weight makes the phone easier to drop. The case openings for the IR blaster, microphone and headphone jack are not 100% dead center, but I wouldn't say they are terribly misaligned either. Openings for camera, speakers, and usb are perfect. I did have some issues with getting certain larger diameter headphone jacks to work with this case, where the jack could not fully insert while the case was on.

Color: White Kit (7500 mAh Battery + TPU) Verified Purchase
TPU case: Sorry to be so negative but oh my god the case just absorbs grime. I posted a photo of it that you can see above. That photo was shot after 46 hours of ownership. This is two days' worth of grime just from body oil from my hands. I wash my hands regularly and I work in IT so my hands are generally very clean. The half that looks white has been cleaned with isopropyl alcohol. The contrast in this image has been enhanced to try to replicate how the case looks in real life. The difference between the clean and dirty sides is actually much worse than the photo would lead you to believe (photo was taken using my iPhone). The TPU case is not smooth and stain-resistant like every other TPU case I have ever had. This case feels porous and picks up dirt very easily!

Battery pack installation: initially very difficult to install because I was taking care to not bend it at all. I finally had to resort to flexing the battery pack, which made the installation very easy. When installing the unit, try flexing the pack to slightly separate the cell with the exposed contacts slightly so that you can slide the "keys" into the slot, then the battery will very easily drop into place. You will not be able to install the battery without resorting to flexing it.

Battery maintenance: I really question the recommendation to run the battery down to 2% on a regular basis. All the Lithium-ion battery chemistries on the market today tend to lose battery life quickest when deep cycled, particularly when run completely dead and then fully charged (thankfully most smartphones are designed "smart" enough to not charge a Li-ion battery all the way to 4.21V). One initial deep cycle does make sense but ONLY to calibrate the battery monitor.
