    The finish on my booster is not chrome as specified in product description
  

*by W***Y on Reviewed in the United States on February 29, 2024*

Everything looks great  but did not come as specified in product description. Not chrome finish on booster. Good deal on what is there but sending a product that is not as advertised  will get 1 star. Don't have time to fool around with returning my time is worth more.
