It’s confused but working
Works well as intended. I may have ordered wrong, but the visual gauge is on the opposite side of original. Still works the same.

Better than oem
Fit my yamaha 07 grizzly perfectly. I think it's better than the oem one.

Good!
A bit larger of a reservoir than the original one on Big Bear, bit of an upgrade I’d say! Works well

It works good
I have to pump my brakes twice to get maxium brakes but one will slow you down pretty good. This was the only 99 wolverine 350 cylinder I could find that worked

Good part
This fit perfectly on my Big Bear 4x4 bolted right up. Has a brake switch which I did not use. I would purchase this product again.
