Just got these JFOYH brake pads as a cheaper alternative to Shimano. First impression? The cooling fin design looks legit, and installation was a breeze—no weird noises or fitment issues.

Performance-wise, they actually brake surprisingly well! The bite feels consistent, and no scary moments on steep descents... at least for the first few weeks. But here's the catch—they wear out FAST. Mine lasted about 2 months (~15 rides) before needing replacement.

The packaging clearly states they're 'compatible with' not 'genuine' Shimano (learned that the hard way after expecting OEM quality). The casting does look rougher than proper Shimano pads if you inspect closely.

For the price? Not terrible as emergency backups or winter beaters. Would I trust them for park days or alpine riding? Probably not. But hey, they stopped my Ripmo AF just fine until the material vanished!

Pro tip: Keep your receipt—the seller seems responsive if you have issues. Might order again when I'm between paychecks and need quick replacements.
