Review on Easycargo Insulator Rubberized Transistor 20Mmx15Mmx11Mm by Douglas Coronado

I'm a fan of these stylish radiators. They dissipate heat really well. And they're badly needed when you're stepping down the voltage with components like the 7805. The only downside is the PCB mounting. If you want to mount them on a PCB you will need a small drill to slightly enlarge the hole for the mounting post. I used a super small hex bit to drill the hole. Just make sure the hole isn't too big. If you can keep the solder ring intact, then securing it with solder is great.
