Love it!!
Size: Iphone 17, Color: Light Blue
I got the Miracase Magnetic iPhone 17 Case in light blue, and it’s excellent. The case fits my 6.3-inch iPhone 17 perfectly and works flawlessly with MagSafe chargers and accessories.
The military-grade protection gives me confidence — it’s shockproof, scratch-resistant, and feels very durable without adding unnecessary bulk. I also love that it comes with a screen protector included. The anti-fingerprint translucent matte finish keeps the phone looking clean while providing a nice grip.
It’s easy to install, feels premium, and the color is subtle yet stylish. If you want solid protection with MagSafe compatibility and a clean, modern look, this is a great choice.

Great case, bad magnet.
Size: Iphone 17 Pro Max, Color: Dark Blue
The case itself is very good. It fits well on the phone. It’s not bulky at all and it seems pretty sturdy. The only problem is the magnet in the back is very weak. Besides that, it’s a great buy.
