I got this with the pre-order for my Note 10+. It's ok, been using it for about a week now. I do like that it is slim and light. It does seem that it holds 10kmA of power unlike others that I have (notably the one that's sold on this site). I really don't use the wireless charging much because my case has a popsocket on it. But because the ring in the center is rubberized, it will probably keep the phone from sliding off easily. The USB C port is only for charging the battery pack, I wish that it was reversible and can be used for sending a charge to the phone. I have a Anker 10k that has that feature. And the Anker has a slower charging feature for smaller devices, which would've also been nice on the Samsung. The lights for showing how much charge is left, is nice and bright. Very easy to see outside in sunlight. The Anker is very hard to see and the lights are not bright. Because they gave me that credit and I wasn't sure what to purchase, I just settled on the changing buddle they offered. If your in need of one, it's worth it if your in the Samsung family of devices. Slightly pricey to me if I had to pay for it, just my opinion. I was able to purchase the Anker for $32, down from the $46 it normally sells for when they had a deal going on for it.
Hope it kinda helps...
