After reading my review the company offered to take care of the problems for me I am very please with the product and amazing seller support. This thing is awesome as a portable desk and or bed desk im using it on a recliner since i can not keep my feet in the downward position .Few problems thought. When moving the cart and the wheel on the right goes under the left it locks the wheel by shoving the lock switch down. But i must say the desk is strong i have two monitors on it using a dual monitor stand and i have a custom gaming pc. Now another problem i had was the item came damaged and not from shipping it was from assembly. Someone at the factory beat the crap out of one of the corners while putting the plastic insert in one side and beat the plastic insert up and broke it. Then on top of that the nut in that hole is the wrong size somehow not one nut fits into it and it free spins even if u could since it is smaller than the cut out nut pattern in the metal. Attached is pictures of the damage. I would ask for a replacement if i did not need this desk so bad and that im disabled and it was hard enough to put this together with my teenage son.
