Rarely uses yes but I have sold 500+ saws and rebuilt quite a many, like I said each has there weaker points, my own hybrid builder needed a new crank, thankfully I mutual friend helped me out, 440/044 is a great saw, to me it took over the 670 champ in the evolution of best 70cc saw, then the 372 OE had its turn now it's really a choice of the 462/572, booth companies bringing out new models is what keeps booth striving to do better. I DNT consider myself a fanboy of any brand, just try and point out the good and bad with any model. Price wise the 7900 Makita is as good as any to me. Point is we should be able to point out things we DNT like and like about each model without being accused of being biased. Stihl guys seem to think the first negative thing you say about a Stihl saw means your bashing it, the 462 finally uses air injection and I love that feature, it's one of the main reasons I purchased one, I am glad they learned from husky, I hope husky does the same with the autotune as Stihl for letting the user reset it in the field of need be, each company can learn from the other, just like we can
