MJannoun,
I like my 445 a lot. So far, no problems; have had it a year. It was bought for me from a box house, a gift for fathers' day.
One thing - keep the bar nut TIGHT. I've slung off and ruined two chains. Bar nut was tight but not tight enough
Pro's: Incredibly easy to start, often starts on the first pull, always by the second pull; once warm, it has never failed to start on the 1st pull.
-Excellent gas economy
-Light weight.
-Plenty of grunt for 10 inch stuff; a little bigger can be done, just go slow.
-I like the decompression release for the decreased strain it puts on the starter rope. I hardly have to pull it all. Rope should last forever.
-Good warranty - two years. dont' lose your receipt
-Somewhat less expensive than a Stihl
Con's: The feeling of the "build" is somewhat cheaper than a Stihl.
-There's only one bar nut, and it's smaller and not as beefy as the two bar nuts on a Stihl. Minor point but I don't like it.
-The brake is not as beefy and sturdy as that of a comparable Stihl. again, just a "feel" kind of thing.
-The handle opening is too small for me to put my foot all the way through it; the Stihl is plenty big enough and also sturdier too.
-Once, when I had the saw buried, the muffler melted a small spot on the top of the cover.
In an apples to apples timed-cut match up series between the Husky 445 and a comparable Stihl homeowner saw, I would bet at least a case of cold beverage that there would be no "statistically significant " difference after say 100 cuts through 10" wood.
There's nothing wrong with the 445. Enjoy it like I have. Keep the chain sharp. KEEP THAT BAR NUT TIGHT.
