Apparently, not all chainsaws are created equal.
Before buying a chainsaw, I strongly advise that you consider different factors before making your final purchase. You need to consider the amount you would be willing to spend, the safety features of the unit, and your knowledge and experience in handling a chainsaw. In line with these factors, you should also reflect on how you wish to use it, the surrounding environment where you intend to use it in, and the maintenance needs of the equipment that you will purchase.
