It's cheaply constructed with particle board but it serves my purpose of freeing up some kitchen cabinet space.  I would not trust these shelves with any amount of weight as the shelves are only supported by the four screws used to mount them to the metal supports with the exception being the bottom shelf has a small metal support leg in the front.  The LED lights work fine and are your standard RGB configuration.  I reversed the installation so the tail of the light strip exits the bottom for a cleaner look.
