Great for the Job
Prestone being a very reputable company does what they do best on delivering great brake fluid. I’ve had no problems to this day with their products. They are great for the money and great for daily drive use. I would recommend a higher grade brake fluid if you decide to use on the track though!

Worked great
Teach your sons/daughters how to learn so they'll learn how to do all of their own vehicle maintenance and save themselves so much money in the future. We've got a couple of guys that have learned everything on their own and are the neighborhood mechanics, which is a good and bad thing, but thankful they can do the job.

Good specifications for dot 4
The Prestone max dot 4 has higher wet and dry temperature compared to other non racing brake fluids.

Good stuff. Was able to notice a difference.
I was actually able to notice a difference in this fluid vs DOT 3. This fluid resists heat better. It stays more springy where DOT 3 feels like it collapses more under heat and load. I like the prolonged service life as well. So far it feels like it will be able to maintain its life through the stated mileage. If you're wondering if it is worth the added cost I would say absolutely. I had new bottles of DOT 3 and don't regret buying and using this DOT 4 fluid instead.

it works
I put it in my both motorcycles, and both my cars (Honda Fit and Hyundai Elantra), and in the honda I also used it to replace the clutch fluid, as it also calls for DOT3/4 brake fluid. Works great, the sponginess of brakes when hot on the Hyundai went away, as expected. The best thing is that it was <$30 and after replacing the fluid in 4 vehicles, I still have one bottle left over. What's not to like about that kind of a deal?

Good size package and good price
This product comes in smaller bottles. When flushing the brake system, I would buy a quart and would have some left. I do not want to save the fluid for any period of time once open. These smaller bottles afford me the ability to keep fresh fluid available.

Works great, tastes terrible
If you're looking for a refreshing beverage that quenches your thirst, then this is not the product for you. If you're looking for some brake fluid for your whip, then this will do just fine.
