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.

I recently purchased a phone case, and I couldn’t be happier with it. The fit is perfect, securely holding my phone without adding extra bulk. One of the standout features is that it works flawlessly with my MagSafe charger, making it super convenient for daily use. The material feels durable and high-quality, giving me confidence that my phone is well-protected. Overall, I would give this phone case a solid five stars for its great fit, functionality, and ease of use. Rating: ⭐⭐⭐⭐⭐

Quality & great price
Size: Iphone 17, Color: Light Purple
Had a silicone Apple case & screen protector from the Apple Store and this one is the same quality if not better. Fits my iPhone 17 perfectly, a pretty lilac purple, magnetic chargers works great and feels good (smooth feeling when putting into pockets or holding)… great price for quality case and screen protector

Good case - not screen protector
Size: Iphone 17 Pro Max, Color: Gray
Case is great as a case. The screen protector? Not so much. Most screen protectors come with their own application tool. This one does not. So you have to do the age old swiping and swiping to get rid of air bubbles. For the case? Definitely recommend. Just pick up a screen protector.
