I giving this item 4 stars only because I was missing some bolts or caps idk what there called is on the pics , i summit an issue on the product and I was able to order more , the estimate arrival is on 2 weeks , regarding the material looks really sturdy the glass is really thick and heavy , my son and I spend a couple hours figuring out how to start the assembly it doesn’t have any instructions, I kept looking at customers pictures to have an idea .
