MS 251 C-BE is rated 4.5 out of 5 by 274.
Rated 4 out of 5 by from This saw is a powerhouse. I love the ease and power of the saw. The only downside is the weight overall. Starts up quick, cuts like a hot knife through butter. Even though it's expensive it's reliability and performance has been worth it so far.

Rated 5 out of 5 by from Good saw. worth price difference between 250 and 251c Easy start.Only small problem the no tool needed chain adjustment is a little unreliable.Must keep close eye chain.

Rated 1 out of 5 by from Chain binds up when cutting when cutting large trees. Disappointed..The Saw is lacking POWER. I believe the toollessadjustment on the side of the saw blinds up the chain after cutting a few hours , lots of smoke from the binding and a large burn mark around the chain sprocket from the binding.,through large Oak trees. plus handle is weak, I cut through a large palm tree and the engine came back to handle and broke the right side and handle fell apart in my hand after having the saw only one and a half months, using the saw daily to remove trees from hurricane Irma daily. Wanting to upgrade to the 271 farm boss.

Rated 4 out of 5 by from MS 251 C-BE Bought this saw to replace a 028 Wood Boss. The weight is nice. Easy to remove limbs and branches once you drop your tree. The Power is not so good. It would be nice if stihl had a demo day to try the saws out before buying. I would have definitely bought a more powerful saw. The Fuel economy is also noticeably bad. I'm adding gas way more often than I feel I should be. The "easy start" is weird but once you learn how it works it does the job. So far the "Quick" Chain tensioning system is working well. All in all it's a good saw. Just uses a lot of fuel and is under powered for cutting 16"-20" trees. I would try to sell it and buy a more powerful unit but the White and Orange plastic already stained badly from use and look awful.

Rated 5 out of 5 by from Best chainsaw I have ever owned. Starts easy. Cuts great. Has plenty of safety features. I was tired of saws that would only work for a couple of years and then be a nightmare to rebuild. This saw is a dream to start once you get used to the inertia system.

Rated 3 out of 5 by from Easy2start is junk, if you can't start a saw with a normal starter you should not be running a saw. I bought this saw used from my local Stihl Dealer. When checking out the guy said this is the deluxe model, I thought oh great. I was very wrong. After a few weeks of using it here and there I went to go start it, the way the user manual suggests and the the pull cord went slack. It would not retract and had no tension. I took the Easy2start assembly off and there was a lot of plastic shavings in there, part number 1123 195 2000 had been chewed up by the flywheel. All the parts on the shaft, the one coming off the starter assembly had come off. The small clip had pooped off or failed. After further inspection the bearings in side the spring housing, part number 1123 190 0700, had also failed. I took it to the Stihl dealer and got parts talked to the people at the dealer and fixed it myself. It worked fine for about a month. Then the same thing happened again. I have used the Stihl MS 170 and 039 never had problems with them. I don't recommend the MS250 C-BE/MS251 C-BE, get the MS250. But the saw did have good power, It would be great without the Easy2Start.

Rated 5 out of 5 by from Nice saw I have an old Stihl 041 which is a great saw for larger material. I needed a light weight saw for cutting smaller trees and limbs. This is a great lightweight saw that starts easily and cuts well. I cut dead cherry and peach wood which is very hard. I just let the saw do the work and it did a great job. The chain is a piece of cake to adjust. I may be a little concerned that the chain oiler doesn't deliver more oil to the chain, but the chain appears to be operating at a good temperature and the oil reservoir goes down.

Rated 5 out of 5 by from Excellent for what is was designed for! Easy to start and light weight for those of us who have had shoulder surgeries. If you have trouble starting it, READ the instructions or have your dealer explain to you as mine did! Power is good for its size. You can cut down large tress with it like I have but this saw was not necessarily designed for that. Love the easy chain adjustment. Looked at “the competitors” but decided on my first Stihl as tired of throwing out other saws after one or two seasons... Not to mention a local repair shop is available. Even if a little more pricey, been worth it so far.
