Bought this less than 2yrs ago, not sure when, may have been a lot less than 2yrs, but broken already. Was that stiff, even though it was kept closed & covered when not in use, that the last time I used it it was stuck in the open position. Had to push it fairly hard to close & it has now buckled & almost snapped on the supporting arm. Not happy at all. Thought it would last much longer than it has!
