So far I've played a few games and it's great I have a galaxy S8 the reasons I bought this one,
1. It does not interfere with the volume or Bixby button unlike other ones have.
2. Its triggers are closer to the screen so it doesnt take much pull on the trigger to shoot or aim.
3. It holds on to the phone very tightly.
4. It has a good feel in the hands and I have bigger hands.
I bought the one without the fan and i do feel my phone getting warm but no warmer then it did without the controller.
The controller I purchased did not have a fan so battery life didnt really apply.
This controller is definitely one of my favorites! First it is EVERYTHING I wanted in a controller. It's like it was designed for the note 8! I can use it both with my case, without pushing my side buttons and with my screen protector with 100% reliability that when I pull the trigger it does what its suppose to without delay
Price it's cheaper than some I've tried and better quality definitely worth the purchase
Comfort over all it is great. Personally I'd like a bit more to grip on to and using it as a kick stand is pointless but neither of those are enough to turn me off this product.
This product is worth the money. You get what you pay for with a little more durability than expected.
