Summary:
Great blower. Two suggestions for owners. First - if you only use 1 section of tube it makes a noticable increase in the CFM. Less restriction = more flow. Second, if you want more MPH you can buy just the narrow tube that comes with the BG85 for about $10 over the parts counter.

Strengths:
This blower has surprising power for a consumer model. The Stihl commercial stuff does not really have much more output. Construction is really solid. I've dropped it pretty hard more than once.

Weaknesses:
It could be easier to start. It always has run for me, even on stale fuel. It just takes more pulls than I would like.

Summary:
I'm happy.

Strengths:
Good for a home owner. Nice not to be teathered to a power cable. The BG55 is pretty stout, its got more power than I expected.

Weaknesses:
Not enough to rip wet leaves off the driveway, you probably need a backpack blower to do that. Could take a few less pulls to start, but I often have bad fuel.
