Nice case for its price. Low buget, does what is needs to do. Have bought one to house a small 1HE server and 2HE router for events. To keep them safe, and for easy transport.
Yes, its plastic.. but the pro is, it bends a bit when hit. The con of this is that when the rack case is loaded with a bit of weight, whole bottom side does colapses a bit.. one rack is now standing on the aluminium rims, instead of his feet. I suspect on the inside its almost resting on the router now.
I have bought another one to house another set of switches, because of easy transport, but when i stack the two together they are not realy stable.. I'ts standing on its four feet, on top of the other case, where i would have expected a recess for them on top of the bottom case..
They slide a bit on each other, but dont fall off. Stable stacking of multiple cases could propose an issue unfortunately..
