Review on 🔥 Easycargo 12 Pack TO-220 Heatsink + Insulator/Mounting Kits for LM317 LM317t L7805 L7812 L78XX Voltage Regulator, IRF Z44N 3205 520N 630 1404 MOSFET Transistor - Silver 20mm x 15mm x 10mm (12 Pack) by Hector Watkins

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