Rated 5 out of 5 by EHitch13 from Great Saw Best saw I have ever owned. Love the easy2start system and the quick chain adjuster. Made easy work cutting up three trees that came down during recent storm. I have owned a Stihl BR600 backpack blower for 9 years and it has run flawlessly. Made my decision to buy Stihl easy.

Rated 5 out of 5 by Professor from A real great machine for a tough job Reading the instructional and safety book is a bummer. But I am a stickler about reading them. But, once that was done it was fun time! This saw is a dream to start and work. I am a human factors engineer and tend to be overly critical of poorly designed equipment. This is certainly not the case here. At nearly my 72nd year it is important for me to trust and be able to effectively work the tools I buy. I find the saw to have good balance, effective vibration dampening, good weight for the power and cutting capability, and dependability. While I would like lesser expensive, the price is comenserate with the quality that is built in. Good machine, "fun" to use, and easy on the shoulders. Just need to make the instructions more "interesting". (How about comic book style, just kidding, I think).

Rated 5 out of 5 by Lumberjakel74 from WORKHORSE Power for the Homeowner I previously bought a "PRO" Saw from another name brand, and took it back after the first week, for multiple reasons. This is my first STIHL Saw and I still cannot believe the difference, compared to the other, this is the " PRO" SAW as far as I'm concerned. Almost double the price I paid,, but TEN times the saw I received compared to the other! Starts easy and idles like it should. I picked up the 2 in 1 STIHL chain file and it works great as well. STIHL ALL THE WAY!

Rated 5 out of 5 by Phil007 from This product meets high quality standards for ChainSaws. "This saw is a dream! So easy to start, light enough not to wear me out, and tough enough to work all day! Chain adjustment is simple and the reduced vibration allows me to cut with a greater amount of comfort and confidence. The STIHL MS 251 C-BE Chainsaw features all the comfort and ease of the MS 251, but is easy to start and adjust on the fly. The MS 251 C-BE is perfect for felling small trees, pruning and thinning, and cutting firewood simply and efficiently. . A Quick Chain Adjuster also makes it simple to put the correct tension on the saw chain without tools. Plus, features like Easy2Start™ technology, a Master Control Lever™ and reduced vibration make the STIHL MS 251 C-BE a lean, easy-to-use machine that still packs plenty of power.
