Great value for money !
The FINISH LINE High Performance DOT 5.1 Brake Fluid is exactly what my bike needed for smooth, reliable braking performance! I’ve been using it for a few rides now, and it’s been fantastic. The fluid has a high boiling point, so it gives me confidence even on long descents and intense rides. The consistency is spot on—easy to apply and it keeps my brakes feeling responsive and powerful. I appreciate that it works well in both hot and cold conditions, and the fact that it’s compatible with a wide range of bikes makes it versatile for any setup. The 4-ounce bottle is the perfect size for my needs and the fluid itself is nice and clear, so I know it’s working as intended. If you’re looking for a high-quality brake fluid that ensures optimal performance, this is the one to go for. Highly recommend it!

Product exactly as described
There's not a lot to say about brake fluid really, other than it seems to be what it is and there's plenty in the tub to do a few brake bleads.
