I have been running chainsaws since I was right around 12 years old. Back then, it was all gas saws and the cordless tool craze hadn't caught on.
I had quite a few trees on my property when I first moved in. Being in colorado where wild fires are common, I knew I needed to get rid of some of them. I was fresh out of the army, I had mostly my mechanics tools and a hand full of carpentry tools my wife had.
We started out clear the brush by hand with an array of tools we picked up at a low price. The smaller trees and the scrub oak brush was easy to clean this way. After that was taken care of we were left with several massive pines that needed varying degrees of limbing and one which was standing dead after a beetle infestation.
Long story short we needed a chainsaw. We had little money so a quality gas saw was out of the question. We picked up the ryobi 18 volt electric saw for a bit over $100. It only had a 10 inch bar, but I was confident in my skills with a saw.
It performed flawlessly for an electric saw. That being said I would like to emphasize that IT IS AN ELECTRIC SAW, you can't compare apples to oranges when it comes to tools. This saw will cut far past it's bar length If you know what you are doing. It operates at constant speed so it will take longer to chew through larger pieces. If the blade gets pinched the saw will stop until it is freed.
Overall, the value to price is well worth it for small scale limbing operations in the hands of a layman and can work miracles in seasoned hands. It's light weight even with the large batteries ( which I think are essential). A great deal of the time I operated it with one hand while in the top of a 40 foot pine. It hand enough power to gnaw through a 12 inch section off the top of one of the pines. Harder wood presents more of and issue for it but for the price you can't expect it to plow through a huge oak.
