Good. I give this 1 star and here is why. This fan blocks the rear. So when the PS5 fans are trying to do their job and push hot air out of the back of the device, they have to wait for this product to blow air out of the 3 holes. Sony created the PS5 for a reason. My family and I use this system for a variety of purposes. Gameplay, Netflix, etc. So on that particular day I plugged this product into the back. The system has been operational for 10 hours. PS5 just shut down. I removed this product and noticed that the back of the unit was hot as if the hot air couldn't escape. I didn't wait but turned the PS5 back on and then checked the back every 5 minutes. it was cooler there. You use this product at your own risk.
