I've seen ads for this product for two years now and it finally came out a couple of weeks ago. It is a great controller, probably better than some actual "console" controllers too. My only complaint is that the triggers feel a little bit sharp against your fingers if you hold the controller in a certain way.
Magnets are very strong as well. I am using a case with an ohsnap on it and my phone is already heavy. I have an S22 Ultra, and it's very secure and there is no fear of the magnets not being strong enough to hold the phone while playing and even upside down it's not going to drop it.
The controller paddles that extend are a bit stiff when you first open the product but after a couple of opennings they're easily deployable and still very strong. Lightweight controller as well.
Ejection is very smooth, sticks are very good I maybe wish they were a little bigger maybe 10 to 20 percent larger but that's just a preference thing. Buttons are greats and you can make multiple profiles to map different layouts for your games to.
This controller is perfect, and I hope it gets the support so it continues to evolve and get better. Hopefully, we get different color ways too, that would be awesome. Overall, a premium product, the price has been a point of contention, but it's worth it with how great the product is.
