    I want to like it, I love the fact that it’s QC 3.0 and it actually quick charges. I like the design on the back it’s grippy it doesn’t slide out of my hand. I wish the frame around the camera and fingerprint scanner was a little bit closer to the scanner I find myself putting my finger there and missing the scanner all the time. And the battery seems to last all day plus I have some leftover plus my phone is at 100% by the end of the day with two to three lights still lit in the back of the case.

    I don’t like the fact that I just looked at my case and I saw a separation at the bottom and it looks like there’s some white stuff I can’t tell if it’s glue or if the battery is leaking on the inside. I like the buttons except for one the actual power button for the case to turn on I find that it’s ever so slightly protruding from the back of the case and if I sit on my phone or if I put my phone down on the table it occasionally begins to charge my phone even if my phone’s at 100% that could be cause for an issue of overcharging. I also don’t like that when I put my phone on the charger it charges my phone first, then it charges the case, and when the case is at 100% it stops charging anything at all. And when I wake up in the morning my phone is at 92 to 94%.

    I’m returning but I’m going to try another case because I do like it it seems to be one of the best ones available for my phone. I just hope this separation thing doesn’t continue to be a problem.

    UPDATE: my replacement is functioning much better. There is no seperation in the case, the button is not nearly as sensitive either. As a matter of fact i have to firmly press it to activate the charge sequence. Ut also appears to so far be shutting off when fully charged so the case isnt draining power which is good. Much happier now that i have a replacement. Seems most my previous serious issues went away. Must have just been a bad one that got through. Updated to 5 stars from 3 stars. Couldn’t be happier!

    I got it just now, and opened it. It is very good case and high-quality. I like it very much. Let me first use it for a few weeks. Then I will be back and give more feedback.

    This is the only battery case I have found that works with apple play and Samsung play without removing case. It’s also easy to grasp in hand and is not slippery like the competition. Also easy to use stylus. Best case on the market.

    I’m happy enough that I’ll keep on using it, but as another customer has said, it only gets you about 1 charge. Also, the description says it has data pass through. I was hoping that meant that it would work with Samsung Dex. It does not work with Dex. Unfortunate, because I use Dex every day.
