We purchased an extended warranty on a Ryobi trimmer. It was told to us at purchase with this extra warranty just bring it back and we will replace it. Well, that does not work. During the first 3 years you must return it to Ryobi and they will determine if it needs a tune up $80.00 or if it defective. REALLY. As far as I am concerned, won't start, its defective. The extra fee plan that Home Depot sells you will only work after the 3 year expires, so I would guess you need to wait 3 years and then return to home depot. Makes no sense at all. Meantime, I just buy another and put the junk Ryobi in the shed and wait.
