A BIG DISAPPOINTMENT!
This unit does not have the power that you think it would. When you activate the self-propelled it starts off really quick for a matter of 2 seconds and then you’re down to a slowpoke pace doing your lawn. The shield on the back of the unit that prevents you from slipping underneath it falls off. The cut from the unit is uneven. It is sluggish to restart if you have to shut off to move some items in your yard. I plan on selling it in the spring and will use it for the next month only. Though it seem like a bargain buy I think I will throw it out for your yard sale at about $100 and hope to at least recover that much. It is definitely a disappointment. I really don’t expect this unit to last that long that’s why after my seven or eight cuts with it I am done. Amazon has no returns on it and I can understand why. Stay away from it and go to your local hardware or building center and buy a quality product. I was in a hurry and did not have time to shop and purchased this item. You only get what you pay for and believe me I didn’t get what I paid for.
