Fortunately I hedged my bets and bought several charging cases of different brands for my trip and although this one failed, others worked.

It was working pretty well for about a month

Having this case charge my while Im working is great.

Got this as a gift for Christmas, it wouldn't charge at first but seems to be working well now

The case is durable and the charge function works really well

This battery case has been in permanent use and is working very well.

But the good news is the battery works great.

perfect, still works and gives me plenty of extra battery

so I've only had the chance to use the case a couple times, but so far it is working very well.

poorly built and the manufacturer wants me to send in the battery on my account due to the faulty work

Looks amazing & works perfectly

This is one of the best S7 battery case I have used so far, gone through two other brands and they died prettry quickly and I needed the power, got this last month and it has been working perfectly for me, recommended for those who are looking for durable and long lasting battery case for their S7

Already quit working after 3 months, junk

This case works wonders

However the battery case stops working on the 33rd day, pretty convenient for them and out of return policy
