A little intro before getting to the topic. I have had rotator cuff surgery twice on the right shoulder, I have a tear in the left that was never fixed, and bad carpal tunnel both wrists. Stuff the vibrates is really bad for my arms/shoulders.
I have fought with my gas chainsaw for years, hard to start, always have to take the carb apart to clean it... it is not rated for modern fuels, and the vibration kills me with pain for a day after.
So I started researching electric chainsaws, a LOT less vibration, no fighting with the carb and hard starting...after reading a ton of reviews I ordered a Ryobi 40 volt chainsaw(I have their 40 volt weed eater, same reasons as the chainsaw! It has 1/10 the vibration of a gas weed eater).
Had a chance to use it yesterday on a down boxelder branch I have been mowing around for 2 years. VERY impressed! Over an hour of cutting, some on 14 inch diameter branches. Almost no vibration! And it cuts as well if not better than the gas saw! 16 inch bar so it is NOT a toy saw like some. It cut better on thick stuff than the gas saw that liked to bog down, the torque available from the electric blows it away. 40 volt 4 amp hour batter, still at half charge after all that cutting.
For the occasional use homeowner who needs to clear downed branches I can highly recommend it! No it is not for the guys who burn wood and cut down 4-5 trees a year. It is for someone like me who gets broken branches every now and then, or to trim back low branches so I don't hit my head on them mowing, or to keep bushes trimmed back to a manageable size. If you have fire pit to sit around and the occasional fire it would be perfect for cutting some downed branches to stack as firewood, not like you are burning 3++ cord of wood.
Price was reasonable, I found mine on eBay from a large dealer, Amazon carries them too.
