For compatible Apple phones up to the se 3, which have a terrible small battery, this is the best solution so we don't have to change them due to their low capacity, as they don't fit their functions anyway.
Removing the case is easy, as the instructions say, for anyone who read them, the phone is removed by sliding it from the top after twisting the case a little at the top.
It adds weight, logical because it has an additional battery double the size of the phone, but it doesn't tire you. It gives a sense of sturdiness. The battery life remains to be seen...

Convenient case for my husband that I bought for him, the only negative thing is that it lasted less than a year, it started not charging

It is the second time I buy this case. Initially, it doesn't look like what you see in the picture. It is thin on the top, but it is not bad. It does its job well. But the battery has a lifespan of 4 months. That's how long mine lasted. Also, the new one I bought arrived with a completely empty battery. So I don't know how long it had been empty and whether this has damaged the battery.

Very good case for iPhone 6s, 7, 8, SE 2020, and SE 2022, which significantly improves the major drawback of these phones, which is battery life. In 2022, I would say that this case is a MUST!

On the negative side: It does not charge the phone and the case simultaneously with a Type C to Lightning cable. Only the case charges even though the phone is inside the case. I tried using a different adapter with a USB to Lightning cable, and it charges normally.

Another negative is that it is very difficult to remove the phone from the case.

Edit: 6 months later, it stopped working.

The reason for the few stars is that it didn't last long.. it stopped charging after 6 months and then it swelled up and stopped charging completely..
