Blastscape for Planetstrike...WHY GW??!!!???

So I advanced ordered the Blastscape from GW simply because it was while supplies last. So I received my order today and damn if I wasnt about to ship the whole damm thing back to them. The quality is terrible! I repeat TERRIBLE!!! The details are ok looking but not great like in the advertised picture. That is why I bought it. It is a thin piece of plastic. If I put my old metal dread or any heavy model on it... it is going to crack and/or dent the shape. It is the same stuff in terms of terrain for italeri and zvezda WW2 models they have. ITS CHEAP QUALITY. So now I have to fill in the bottom with some heavy strong plaster or even green stuff to give it some rigidity and durability as terrain before actually basing it. For the price I would have thought better. Damn was I duped! below is my video and I am still upset. I even end up messing it up just applying some weak pressure in the video. Well I am done. Take from this what you will. I just needed to vent. So I feel duped and I over paid.
