MS 251 WOOD BOSS® is rated 4.4 out of 5 by 251.
Rated 5 out of 5 by from Quality saw that is very dependable Bought the ms251 to cut down dead elm trees on my property. So far has performed flawlessly after cutting down over 30 trees, some almost 3 ft across. Keep the chain sharp and it goes through wood without issue. Starts right up and never stalls. Worth a few extra bucks over the saws you get at Home Depot or lowes.

Rated 5 out of 5 by from best chain saw I have ever owned Would recommend this chain saw to everyone! Starts every time & runs consistantly.

Rated 5 out of 5 by from 3rd week after Log Cabin purchase. Beats the previous saws I have had. We had a wind storm down over 200 trees. I burned up a box store cheapie. The next weekend a bought a Stihl MS251 and never regretted it. It took a week to before I drive all the way up my driveway to our cabin. A year later I am still working on cleaning up the mess upland. The Stihl starts and runs on demand. Has never given me grief. Cuts twice as fast and is more predictable previous saws I have owned. I would buy another Stihl but realistically I don't see me ever needing another saw. Time will tell.

Rated 3 out of 5 by from Restarts poorly After the saws been running and then you shut it down, you go to restart it within 5 minutes it starts very poorly have to pull it 20 times. Had a 35 year old wood boss was a much better saw more power more reliability.

Rated 5 out of 5 by from Best chain saw on the market. Best saw thus far. Very dependable and easy to handle.

Rated 5 out of 5 by from Very nice saw I have had the saw for about out year. It starts up every time with out a fuss. ( I put full choke on, pull 2-3 times ( it stutters), put half choke on, pull once, let it run for 10-15 seconds till the chain starts spinning, turn choke off and start cutting)Cuts great. I have been using it to clear my wooded lot that I plan on building on in the future. So far I have cleared a 20 x 220 path for my driveway. The saw has a little bit of weight, but not to bad. There is not much vibration as I'm cutting. The location of the gas and chain oil is very nice, easy to poor into with out making a mess.
