The only thing I dislike is how the large battery limits your cell service in places that are hard to find signal already, but I expected that

Awesome product and service

Messes with the reception in certain areas where I used to have fine service which is why its only 4 stars.

Great Customer Service!

, I believe 5200mAh,and the battery life is great and still have good service

Anker has fantastic customer service & I will most definitely be ordering Anker products again!

It doesn't interrupt my service in any way.

haven't charged my phone in 4 days and it doesn't loose service.

Great product, great customer service

well done product with even better customer service

Update: Great Customer Service

for that I added one star, because they do have brilliant customer service.

Good customer service in this day in age is rare

GFood product, excellent service, thanks.

That does not bode well for good customer service

Excellent customer service

Usually their network is pretty stong in our area with comprehensive 4g service but with this battery I have low bars on 4

Updated to 5 stars, great customer service.

but then I was force to pay shipping to return an item that was not what I wanted, had confusing labeling and instructions, and rude customer service.

still good company and good service jus product wasnt for me.

I did notice that if I am in a weak service area (like one bar) , I may actually lose service till I get to a different area, but other than that , the case that comes with it is nice.
