So far so good
I have had so far a mophie air pack and a unu Dx charge case. My first mophie air worked for 2 years but the connection of the case stopped working not charging the case. I then purchased a UNU DX case which the battery capacity was awesome charging my whole phone plus having extra. However it only lasted a year the cause was it stopped charging the case. I decided on the mophie again because this one had a larger capacity than the Mophie air but seems to have better quality than the UNU. First case I received stopped charging the case fully after two weeks charging all not and only going to two dots. I tried various methods to fix the issue with no success. I contacted Great Offer Stock and they replaced my case no charge which A+++++ to Great Offer Stock. I received my new case again and so far so good after 2 weeks. I learned if your case is fully depleted you need to charge it removed from the phone. Otherwise it will not charge fully leaving you a half dead case in the morning even charging it for 10 hrs. Also when the case is fully charged it does not have the capacity like the Unu which I miss. So far will have to see but would recommend the UNU to someone because of the ease of charging and larger capacity.
