Useful in small places like my flowerbeds especially in established ones where things can get tight. This is a beginner unit with the least power but powerful enough to use in small residential landscaping and flower beds. It is easy to assemble as you only need to turn two knobs to secure the handle and push two rings through either side of the blades. Because it runs on rechargeable batteries, you don't have to worry about cords getting in the way. There is an extra battery so you always have power. You have at least a solid hour of power and the next battery will be charged before then. The unit has a helpful control handle which I used to force the unit down to dig further. The power handle has a button to hold down the power button for you which helps alleviate hand stress. Unit is light weight, stores easily, and has a nice color. It was extremely affordable.
