Is the Walmart version a different grade than the one sold by Pyramyd? I thought a lot of Walmarts stock of any product were special made for them only, to shave off quality for a lower price that would be unoticed by the customer. But results in in breaking earlier/easier than if you had bought it elsewhere.
Actually, many manufacturers try to insure quality at a higher level for the mass-retailers like Walmart. Why? Because, where PA or other smaller stores may send back or return items one by one or 5 at a at a time, stores like Walmart tend to stockpile returns in bins and send them back en-masse. Makes sense, since a typical defect or problem could show up in 1000's of units at Walmart.
