This is my second cover for my Galaxy S8+. The first one, same type, only lasted a year. So, something to note is that unlike the Otterbox covers that are made of durable plastic, these just won't last as long. Also, screens can crack even with this cover since it's not sturdy like an Otterbox.
That being noted, the good stuff outweighs the bad. I'll treat this cover as if it wasn't a cover but a fragile screen so maybe it will last longer. If you get a thicker, sturdier cover, you won't be able to wirelessly recharge your phone. This cover allows me to keep the cover on and wirelessly recharge. This cover also has cool functions like being see through when the phone wakes up. If you get a call, the screen will show up through the cover and you can accept or decline without even opening the cover! If you hit the side power button, the date, time, % power left and some alerts will be displayed (or whatever you set your phone to show out of Samsung's choices). And finally, the front cover, when the phone is sleeping, is actually clear and reflective enough to be a mirror. I liked this cover enough to buy another one when the reflective sheet on the front of my first one started peeling off. I removed it, thinking it wouldn't matter, but then the front started falling apart. Had I known that, I'd have kept tamping down the sheeting.
