Why spend $189 at Home Depot when you can get this for $99? The trimmer arrived and was in like new condition. It started right up and runs great. It has plenty of power. Best of all, no more keeping gas and oil mix around. The down side is that since it is a 4-stroke with an OIL pan of sorts, the edger only operates in the basic trimming position. It you tilt it too much in any direction, oil will enter the cylinder and start smoking. If you continue to run this way, the engine will stall and oil will run out of the carborater. So what this means is it is not very friendly for attachements such as hedge clippers or chain saws and such that you need to run at varying angles.
I am fine with this because I really just need this for the basics. I have the edger, trimmer and blower attachments, and they all work great.
