Review on Heatsink Aluminum Radiator Amplifier Transistor: Optimal Heat Dissipation for Enhanced Amplifier Performance by Jeff Payne

The heatsink is fairly basic and should be perfect for the intended application. The width and height are just right for the back of the Nema17 stepper motor. Although the ribs are a bit sharp and can be dangerous (especially when mounted on a moving axle) and the self-adhesive backing allows for more direct application, the main issue is that one of the items arrived damaged with the ribs crushed due to inadequate packaging . The recycled envelope was good intentions, but despite claims of being as efficient as a cardboard box, it doesn't provide adequate cushioning for shipping. finished and it's still usable but doesn't look "factory" if you're worried about the aesthetics.
