Great product however what you plan to.mount this to makes a difference. Originally purchased to attach to a veridesk standing desk convertor. I found the stand/arms to be solid in construction and they didn't "melt" or droop over time. 

With that said when we redecorated our den/home office and purchased a glass top standing desk, the metal frame was not sufficient nor was the desktop portion thick enough to support and we had to purchase a different model. Total bummer because these are great value for the money. Highly recommend!
