Review on Easycargo Insulator Rubberized Transistor 20Mmx15Mmx11Mm by Bob Schultz

This is a good and cheap heatsink for TO-220 components like LM317 and 780x bis to 800mA. Suggestion: For more powerful devices, use silver paste instead of pre-cut silicone and take the time to sand the back of the heatsink with 600 grit until you reach the bare metal. It makes a world of difference. and your device will run significantly cooler. Decent quality, especially for the price. I will buy again.
