I used them to cool the peltier chip. The contact surface is nice and smooth, which allowed me to use a minimal amount of thermal paste. I added a fan to the fins to help airflow. Fits my project perfectly.
Good workmanship. The information was correct and the edges are clean. Not quite enough to cool Peltier elements even with a fan to dissipate heat and thermal paste, but will probably do for other light applications.
Even smartphones. Mine uses a 25w charger. My phone gets a bit warm if I let it charge on its own when it hits 25W. I put two of these on the screen and it stays much cooler while charging. This prolongs the life of my phone, including the battery.
