I have the iPhone X: I thought the charger for my iPhone like $50, so while researching this seemed to be cost effective to test, just to see if I would use even use a wireless charger. If it didn't work well, I was only out $10-$12, not $75. It works great.Note about the adapter: the confusing part for me when I was researching some of these chargers before buying this one, was the "no adapter included" (at least for me - i was wondering if its a Special adapter I had to buy separately or something, it is not). Most of us probably have a bunch of wall adapters already so they don't bother including it to sell it cheaper; This vendor recommend using the original manufacturers adapter (EG Apple) so I used my Apple adapter plug that goes into the wall. I had a bunch, already and they provide the cord which is just the micro-usb standard one, so everything is standard on this.For wireless charging with a case: I bought a thin case previously for my iPhone (spigen I think), it's the thin one and I don't have to take it off. I place it on this at night, or before work to top it off and it charges pretty fast but I should note i'm using the Apple iPad adapter (the bigger one - 12w, versus the one we get with phones the smaller 5W one so that might be why). There is no difference I can notice between this and any wall charger in terms of time to charge, but I didn't test it just my observation.This is great at night - when ready to go to sleep, you don't have to turn over, find your charger cord on the nightstand, plug it in while its dark like some mind puzzle trying to find the hole in the phone, plug it in, then turn back over. I flop my arm over, look for soft red light and dump phone right on top, my phone makes the 'bong' sound of charging and screen lights up so i know its on as well as the green light comes on. As the description says, the green light doesn't go off or disappear when fully charged - doesn't bother me at all how I'm using this (not a quick charger).When it is not charging, the is a soft red - but not annoying at all, I dont notice , i actually have to look for it when ready to put phone on it. However, it's on my nightstand so not facing me.Placement: I don't have to be very careful where I put it to have it charge, but you can't just toss it and have any part just touch it either, just generally put center of phone near center of this charger and your'e good, even an inch or more off.I will now buy one for the door as i walk in from garage where we put phones to charge after the day (Iphone 8s for the kids/wife). I'm sure other phones might work better, worse but at least for us with the original adapter from Apple and iphone8 and X, works awesome.NOTE: I've attached pictures - I kept my wired lightning charger for size reference (I still use to charge ipad which isn't wireless).First with light on in room, second with light off and flash off to show light brightness, very muted so perfect. Last is with iphone on it when i just placed it, see light turn green. Phone screen goes dark after obviously, i don't notice green light bc its not too bright and also on desk next to me
