Overall Assessment

Customers appreciate the aesthetic and functional value this product adds to their hot rods. The chrome power brake booster and master cylinder perform well, making it a great addition. However, some users noted partial chrome coverage in areas of high visibility in certain applications. Despite this, customers are satisfied with its appearance and practicality. The product was described as 'nice' and 'working great', clearly winning over competitor options. Some suggestions point to improving chrome application for an enhanced appeal, but overall, the product is highly recommended.

While the part works fine, the grinding and smoothing before chrome does not extend to the bottom of the housing. In my hot rod application, it shows.
