Extensions went together easily. Saw worked great and cut through some good sized limbs. I had a lot of trim work to do in my yard and decided I wasn't up to using a manual pole saw. This attachment worked great and the job done in about six hours.
I bought 2 of these over the years. They work for a while but they are poorly built. Their Nylon Guard is plastic and the screw to tighten the chain saw blade will go through the housing.because it is plastic. I suggest putting a metal plate that the screw can go through and the screw will not break the housing. I am now looking for a attachment that has a mental housing.
I have cut through some serious logs (like 8-12") with this little attachment. I'm not necessarily recommending it for that, but proves the point this thing is really strong. It works great for branches and such and the reach is nice.
