After using this blower for a full 12 months, I can easily say that it is quite possibly one of the best values on the market today in a hand-held blower. My previous blower, a Shindaiwa EB-500 was a great machine. Yet at nearly $400.00 and with similar performance numbers, it is in no way a value. So how did I come across the Echo? Well there I am....blowing down a sidewalk after a mow, when my Shindy gives up the ghost. So now I'm in a pinch. I head down to an Ace hardware store that I knew sold Echo. I pick up a PB-251 for $169.00, drive back to where I left off, filled her up, and was expecting a less-than-optimal performance of a hand held blower. "BWAAHH! BWAAAAHHHHH!!" Whoa, this is a hand-held? This little thing put out more air than my backpack ever did. Official numbers are 145MPH and 509CFM. That would be about average for a backpack, but exceptional for a handheld. It does struggle if you have large amounts of wet leaves, but for the daily maintenance crew you can purchase 2 of these for the price of one backpack blower. Mechanically, I have had no problems with it. One time it started to bog down when it got hot, but a quick cleaning of the muffler cleared it right up. This is certainly one little blower that I am glad to have working for me.
