Giving it 4 stars because instructions would’ve been nice  what worked for me it’s installing it upside down, then putting in the flat rings with bolts(make sure it’s extra tight so there’s no wobble). This table is actually very sturdy if done correctly Also the middle ring is needed or else middle part connection will look out of place(in my photos, I later fixed it). Lastly, use a vacuum to clean the dust under the glass. Toodles
