After spending money here and there to get separate heatsink kits for my ever-growing Raspberry Pi collection and a similar collection of SBCs (which always came pre-assembled with tape), I decided to buy the kit in bulk buy it so I always have it with me. I should have paid more attention as they arrived without glue so I have to order now and wait for the hot melt to use. If you already have thermal tape, glue or paste this kit is perfect. Otherwise, shop around and you can find several heatsink kits with pre-applied adhesive at a price close to this price and a tube of hot melt adhesive or a roll of thermal tape. However, the quality of most of these radiators is quite good. , especially black anodized ones. Smaller plain aluminum ones are fairly common, but far fewer than anodized ones.
