Review on Lot of 5 Chrome Plated Wal-Rich Radiator Air Valve Key for Bleeding by Brent Porter

I've tried them on several heatsinks and haven't had any issues with bleeding. They don't feel like solid metal, but I was able to apply a decent amount of torque without cracking/buckling/cracking. Not a bad deal, I paid about $11.50 for this 5 pack as many Revain listings on these items are over $10 each. You can find better ignition keys at a hardware store for a lower price but if you want to save money visiting a hardware store with premium shipping these are great.
