These OEM bars are real performers. Power and ergonomics realy don't play a part here but I wanted to give it a full 5 stars. I am a big believer in usng OEM parts for maintennce and repairs and these bars add to my beliefs. My 445 performs like a dream paired with this 16 in. bar and the H30 chain. The oil injecton ports have never clogged and the roller tips are sturdy and last the life of the bar when properly maintained. No bar lasts forever but they last as long as any Oregon or Carlton bar I have ever used in the past. You do however need to keep them out of the dirt, roller tip bars don't fair well If you get in the dirt. If you like using original equipment on your saw you can't go wrong here. Highly recomended product.
