The unnamed heat sink has received positive feedback from customers. It is noted that several customers used this heat sink to cool down different electronic items, such as a resistor, amplifier, phone, and a LED grow light driver. Some customers also mentioned that the product is well-made and made of good quality. The format of the review indicates that the product has not been extensively reviewed and used by many customers. The heat sink is reflective, which may suggest it is anodized, but there is no clear evidence on this. It is slightly smaller in size and thinner in fins than expected, but it fits well for some particular electronic items. Some customers have also recognized that they secured the product with thermal epoxy. The thermal resistance of the heat sink varies by the length, and there can be improvement with forced air flow.
