They work. Simple as that. It's several tiny, tiny aluminum radiators with self adhesive thermal pads. No visual defects on my order
Depending on the size and temperature of what you are trying to cool down, the miniature size of these ribs might be too small. You can't attach a fan to them(which isn't really a con, since that's obvious) so you rely on whichever air movement you have already.
I used several packs of these in an experiment for my graphics card in a hope to reduce the temperature during crypto mining. Previously the second core was at 100-103 degrees Celsius at 60-70% fan speed - which is LOUD. Now the second core is STILL at 100-103, but the fan speed at only 50-60%, which is a huge improvement. The cooldown time after use is also slightly shorter.
Great heatsinks at good value. They are SMALL! Buy several bags if you plan on using them for something larger. Supereasy to attach due to the self adhesive thermal pads - BE ADVISED, this is a one time only thing. If you mess up you probably won't be able to re attach it with the same pad.
