As good as as5, much better value
Works very well. No real world benefit over more expensive types per gram like as5, etc. Fanboys won't want to hear this, but every thermal compound made with "99.9% pure silver" is 99% silicone grease and a negligible fraction of carbon or silver of that purity. It's like "made with 100% real cheese" on cheetos. I've tried them all, and this tube will last me 10x as long as as5 and it works just as well.
