When purchasing an item at Walmart that needs a warranty you must be very careful. Why you might ask? The reason is that Walmart will not stand by it's warranty.
Just to give you a simple case: We purchased a lawnmower with the two year warranty and after three months; it broke down. The warranty provider told us to bring the mower to a place to have it repaired. Okay, I got the patience to that so; we called them and we were informed that it would be at least three weeks before they could repair it.
Next step I did was calling Walmart to see if anything could be done to help us. The manager told us he could not help us and we would have to deal with the warranty company. Even though Walmart sold us the warranty? This is a disgrace! It did not matter so; we are at the mercy of the warranty company and the repair shop.
I would recommend never purchase any large items from Walmart and you will be better off buying from another company like Home Depot or Lowe's. You may pay a little more but will not be rip off by the shysters' at Walmart.
Let them keep their inferior products! Buy in other stores and save yourself a lot of stress.
