This unit is easy enough to assemble and sturdy once mounted to the wall with the included mounts.  The doors are lightweight and easy to open/close, but the acrylic glass is tinted rather darkly, making it difficult to see items inside without using the LED lights.  The LED lights are nice and include a proximity switch that can turn them on when you approach however, they only work when standing directly in front of the cabinet and one switch out of the five cabinets I purchased was defective.
 
Update:  The acrylic is tinted so darkly, I am going to have to replace it to make my display items visible.
