    4.0 out of 5 stars Seems like a great product for the price installed yet but looks very easy to install
    Reviewed in the United States on February 24, 2022
    Great product for the price and seems well made and easy to install with all needed fitting. (Even included stainless steel hose clamps which is very unexpected at this price point) (also came with good instructions not written in clear English, also very unexpected at this price point) only thing is it could be packaged better, it arrived with minor damage to the ends of the fins, but it should not effect the cooling ability or usability of this product at all. Overall very happy.
