Mahle Original Premium Piston Ring Sets
Mahle Original piston ring sets are designed to be installer-friendly. They are pre-lapped to seat immediately, virtually eliminating break-in time. Ring materials and coatings, as well as ring tension, are all optimized for reduced friction and extended life in each application. The compression rings feature a barrel-faced contact area for more efficient compression and CNC-controlled gap chamfer to optimize compression and reduce blow-by. Intermediate rings have a reverse twist design for better groove side sealing, and taper race machining to enhance contact. The CP-20 oil ring assemblies feature a 20 degree ear angle, an exclusive feature that provides the best possible side seal against the cylinder wall, and a special chemical polish on the oil ring expander offers enhanced oil drain back. Mahle Original piston ring sets provide unmatched quality and ease of installation, making them the rings of choice for today's engine builders.

Screen protector
Size: iPad Air 11" M4/ M3/M2, Size: iPad Air 11" M4/ M3/M2
I’m really happy with this screen protector for my iPad. The quality feels really good, and it fits perfectly on the screen without affecting the display quality or touch sensitivity. I was worried it might make the screen look dull or reduce responsiveness with the Apple Pencil, but everything still works super smoothly. It also helps reduce fingerprints and keeps my screen protected from scratches, which gives me peace of mind while carrying it around daily.

Good protection, but some bubbles remain
Size: iPad pro 13'' 7th (2024), Size: iPad pro 13'' 7th (2024)
This screen protector does a great job protecting my iPad. It feels solid and the screen still looks clear and responsive after installation. Overall, it gives good peace of mind for daily use.
Installation was simple and straightforward, which I really liked. It didn’t take much time and everything you need is included.
The only downside is that there is always a small air bubble that stays under the screen at a certain angle and doesn’t fully go away. It’s not a big issue, but worth mentioning.
I’ll attach photos after installation so you can see how it looks.
Overall, a good product with minor imperfections.

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.
