For the price, I thought the quality was great. It arrived damaged. However that's more than likely due to shipping as the plastic lid was broken. I am overall happy with this and I would purchase again in the future.

Self propel

I was happy with the purchase, but then myself propel just went out and I've only used it three times I paid for protection. I want them to fix it.

Tires are so slick

The self propel works great but the plastic wheels make it impossible to mow on a hill. I happen to live in the mountains and my whole yard is a hill. It slides around like it's on ice. 😢
